MD:
Defs:
- var definition
- function definition
- function argument definition
* AST_VarDef
* AST_Defun
* AST_Function
* AST_SymbolFunarg
Levels of follow:
1 level: Simple types: String, Number, Boolean, Function.
2 level: Arrays and Object ( Array<val_type>, Array<key_type, val_type> ).
Deep : interfaces, classes (prototypes), singletones.
Operations to check:
* AST_Return
* AST_Call
* AST_UnaryPrefix
* AST_UnaryPostfix
* AST_Binary
* AST_Conditional
* AST_Assign
Warnings:
* type mismatch
* redefinition of variable
