v0.2.0 Lots of Fixes

• Created interfaces are now held in shared_ptr to avoid dangling reference issues.
• 2D Arrays have a special case now.
• Added "custom_value" for custom value parsing/generation
• Fixed Readme Whitespace
• Added clang_format file (Not all files were reformatted automatically)
• Fixed some clang warnings/errors
• Created slots are now returned as unique_ptr, and not as an owning raw pointer (YUCK) anymore.
