* adding methods to the ast * pre commit stuff? * implementation of class functions * implemented methods * some cleanup * more cleanup * add newlines in test programs * pre-commit fixups * added include of return_term.h * a test of a method calling another method * replacing Member with Declaration * removing the member.h etc files * clarify a type annotation * update uses of FunctionDeclaration * remove ReturnTarget, no longer needed * more cleanup * more cleanup * yet more cleanup, playing with pre-commit * did a pre-commit run --all-files * fixed const issue * remove comment * checking dependencies in BUILD files and headers * pre-commit working now * refactor NominalClassType to just hold a pointer to the class declaration * remove Member from rtti * responding to Geoffreys review * change field_types to a non-member function
