Fixes: Maintaining schemas is difficult and error-prone - Facilitate easy schemas add, remove, change, etc. - Remove 14 files containing approx 2,190 lines of if/else code and data - Place data in one file (UnitsSchemasData.h) using a normalized structure (including special functions) - Isolate and simplify data operations (code) - Remove schemas enum to keep data independent of code - Separate responsibilities: Specifications, data, schemas, schema - Add schema data 'isDefault' - Add schema data name - Prefer algorithms to raw loops - Add schemas unit tests - Tweak quantity unit tests
