------------------------------------
* Descriptor should use a map to cache common conversions
v. good.
* CodeContext should avoid allocating unneeded objects
* CodeContext should double code size when growing it
v. good.
* Methods should be cached by name
v. good.
* switch finding LocalVariables to push the information down the tree eagerly instead of searching up it lazily
v. good.
* add the ability for SimpleCompiler to cook ASTs directly
v. good.
* UnitCompiler should push a local variable map through the tree
v. good.
* add more tests
