Title: added support for string fact names

added debugger into dev deps

- internally facts are still stored as array of symbols
- api assures that facts could be defined only as symbols or strings and accessed in either way, which is the purpose of #ensure_symbol method
- when fact is defined in the Base class we return it wrapped into an object with additional api - to simplify the logic outside, which is the purpose of fact_functor_obj
