* Optimizations with private, params, and isEqualType * Fixed tab being used instead of space * Fixed tabs inserted by notepad++ * More usage of new private syntax and params - changed a few checks for an array being empty to `_arr isEqualTo []` rather than `count _arr == 0` - added more uses of `private` on the same line as the variable is declared - added more uses of params to assign variables passed as parameters - removed unnecessary parentheses - removed several unnecessary variable declarations with private array syntax * clean up and formatting
