RANGE: Most of the code is redundant and hera as inheritance boilerplate.
The added/edited code adds logic for handling range / non range mode.
Additionaly, in range mode it will apply logic to mark the dates within the active month
that are within the range.
There are 3 range states for a month view, set by the combination of "_rangable" and "_allInRange":
- Not rangable (single value datepicker OR active month not in range) - _rangable = False
- Rangable but not all (active month is partially in range) - _rangable = True
- All In Range (active month is in range, start/end dates before/after this month) - _rangable = True & _allInRange = True
