Adds enough to build the AST nodes for the module function declarations in a .em file. Adds: - Function: base class for module function declarations and user functions - FunctionParameterDeclaration: declaration for a function parameter, as well as its default value if any - FunctionParameterList: just a holder for function parameter declarations - ModuleFunctionDeclaration: for function declarations in .em files - FunctionResolver: hooks up function calls to module functions or user functions - ModuleProcessor: a visitor for processing const declarations and module function declarations (const declarations are yet to come from the main branch)
