Fixes 65851410_about_symbols_master

* Learned that symbols are symbols
* Learned that symbols can be compared like strings
* Learned that Identical symbols have the the same object_id
* Learned that method names become symbols, however, constants do not become symbols
* Symbols can be made from strings with spaces and interpolation, but are not themselves strings
* Symbols can't access cool string methods because, although they are immutable, they are not immutable 
  strings
* Symbols cannot be concatenated, but they can be dynamically created using concatenated strings (still not a 
  good idea)
