Refactor and New Features

-Changed: Refactored some variable names because they got out of hand since they were handed for single cases instead of making actual specific rules.
-Added: mapping functions (only to objects) are now accessible to primitive collections.
-Added: Filter function for Iterables/Iterators. (Iterable implements them automatically)
