* Dependency
- When a variable declaration has a kind-of type we are unaware of then print out an error message before asserting `false`
* Builtins
- `getBuiltInType(TypeChecker, string)` will now return a `Pointer` object for arrays of which the type was `<componentType>[]` (non-stack bound) as effectively they are pointers with a different syntax -doing it here means that it is transparent and typechecking, code gen and emit will just see a pointer type which makes life a lot easier
* Builtins
- Added information about the current bug faced in issue #81 (third sub-issue)
* Test cases
- Updated test case `simple_arrays2.t` to show case bug sub-issue 3 in issue #81

* Builtins
- Updated TODO
* Builtins
- Removed comment as now fixed
* Array
- Added `getComponentType()` method which will return the array's element type
* Dependency

* Builtins
- Added `bool isStackArray(string)` in order to check if a given type string is designated as a stack-array type or not
- `Type getBuiltInType(TypeChecker, string)` now can generate the `StackArray` type including the component type and the size of the stack allocation
Parser
- Added support to`parseTypedDeclaration` to be able to parse stack-based array types
- Added terminator `]` to `parseExpression()`
DGen
- Added stack-based array type transformation support to `string typeTransform(Type)`
- Added transformation support for stack-based arrays for the `VariableDeclaration` instruction
StackArray
- Renamed `Array` type to `StackArray`

* Parser
- Working on adding array index assignment support
Test cases
- Added test case to test array assignments with
* Parser
- We can now detect when infact we are doing an array-indexed assignment and when not, we then flip` arrayIndexing` to `true` if that is the case and ensure that `=` SymbolType.ASSIGN is not triggering the varaible-declaration-with-assignment but rather eters a different branch based on this boolean
- Set the identifier being assigned to (in the array indexing case) to the `type` with the `[]...` stripped
Notes
- Added a TODO file `wip.txt` with notes about what is to be done for adding full array support
* Parser
- Handle the case whereby `SymbolType.ASSIGN` or `SymbolType.IDENT_TYPE` is not found by throwing an error
* Parser

* Parser
- Added right-hand side expression parsing for array assignments
Test cases

* Instruction
- Added new instruction for indexing into arrays, a new `Value`-type instruction called `ArrayIndexInstruction`
* DGen
- Handle `ArrayIndexInstruction` which is for whenever you index into a point-based array (an expression like `myArray[i]` is now being supported in emit (first steps))
* Instructions
- Added a new instruction type, `StackArrayINdexInstruction`, which is used to know when we are indexing into a stack-based array rather than a pointer-based array (just to be able to disambiguate between the two)
- Added a work-in-progress type `StackArrayIndexAssignmentInstruction` which will be used for assigning to stack arrays at a given index
* Instructions
- Added implementation for `StackArrayIndexAssignmentInstruction` which represents the assignment of some `Value` instruction to a stack-based array (indicated by the `arrayName` string field) at the index indicated by the provided `Value` instruction
* DGen
- Added a stub emitter for `ArrayIndexInstruction` (pointer-based array indexing)
- Added a stub emitter for `StackArrayINdexInstruction` (stack-array based array indexing)
* INstructions
- Added `getArrayName()`, `getIndexInstr()` and `getAssignedValue()` to `StackArrayIndexAssignmentInstruction`
* Instructions
- Added `ArrayIndexAssignmentInstruction` which is intended to be used for when one wants to assign into a pointer-based array
- It embeds a `Value` instruction which is what is to be assigned and then an `ArrayIndexInstruction` representing the base of the poiinter-based array (base address) coupled with an "index" (offset)
- Added a `toString()` override for `StackArrayIndexAssignmentInstruction`
* Test cases
- Added `complex_stack_arrays1.t`
- This tests a stack array of a fixed size of `int[]` (basically `int*`) and assigneing into it
* Test cases
- Added `simple_arrays4.t` which makes an `int[]` (which is an `int*`) and then assignes into it at `i` whilst referring to itself at `i` and doing a binary operation
* Test cases
- Added `simple_stack_arrays2.t` which tests a stack array of a fixed size and then assigns into it a value
* Test cases
- Added `simple_stack_arrays4.t` which just tests assigning to a stack array of a fixed size BUT referring to said stack array itself as part of the assignment expression

- The indexed expression (the entity being indexed) will be depended upon
---
- Added dependency generation for `ArrayAssignment`
- The `ArrayAssignment` parser node will be pooled
- The `ArrayAssignment` will have its context set to the current context
- The assigned expression will be depended upon
- The entity being indexed will be depended upon
- The index expression will be depended upon
* Parser
- Added a branch to `parseName()` which handles array assignments's semicolon consumption and token cursor movement to the next token

- Disabled the intentional `assert(false)` when handling array assignments
- Assign the generated `ArrayAssignment` to the `generated` variable
- Updated `parseExtern()` to cast to `TypedEntity` to ensure that the `Statement` returned is of that sub-type (added an assertion to then check this fact)
* Typechecker/Codegen
- Implemented `isStackArray(Value)` which checks if the given `Value` instruction is a `FetchValueVar`, then extracts the `Variable` being referred to in said instruction and checks if its declared type is that of `StackArray`
- Implemented code generation for `ArrayAssignment`
- Implemented code generation for `ArrayIndex`
* Test cases
- WIP: Added `simple_stack_array_coerce.t` as we want to add coercion for this now
* Typecheck
- Added rudimentary check for checking if an argument is a stack array, and if the parameter (to a function call) is a pointer and if so then returns whether they have matching component types in a new function named `canCoerceStackArray(Type, Type)`
* Typecheck
- Fixed `canCoerceStackArray(Type, Type)` to actually coerce the first type first into a pointer type (coercing the stack array's component type to `<compType>*`) and THEN apply the `isSameType(Type, Type)` check
* Typecheck
- Hoisted up `canCoerceStackArray(Type, Type)` to the class-level of `TypeChecker`
- Removed debug prints from `canCoerceStackArray(Type, Type)`
- Added a TODO where the check should be done in the `FunctionCall` branch of the `DNode` processor
* TypeChecker
- Added a seperate check for function call `DNode` processing which now checks if we can coerce the stack-array-based argument to the pointer-based type parameter
Notes
- Emit now fails as we haven't implement an emit for this case, so we need to do that.
- Also, should we change the type of what is being passed in - perhaps that actually makes sense here - we haven't fully coerced it actually
* TypeChecker
- Updated `canCoerceStackArray(Type, Type)` to now take in `canCoerceStackArray(Type, Type, ref Type)` to set the newly created coerced type
- Fixed bug whereby if the coercion succeeded we didn't actually add to the list of evaluation-instructions in the `FuncCallInstr` object, hence there would be a `null` Instruction object appearing in the code emit phase.
- Added some NOTEs which we can clean up this code using

Parser
- `parseFuncDef()` now accepts a default argument (set to `true`) on whether to expect a body for a function or not, in the not case expect a semi-colon - this helps with extern support
- Likewise because `parseFuncDef(bool wantsBody = true)` is called by `parseTypedDeclaration()` we have added same argument to `parseTypedDeclaration(bool wantsBody = true)`
- Ensure we pass the parameter from `parseTypedDeclaration()` into `parseFuncDef(bool)` in function definition case
