Supported operators:
- add, subtract timedelta
- unary plus, minus, abs
- compare to timedelta
- multiply, divide by int
In addition, datetime supports subtraction of two datetime objects
returning a timedelta, and addition or subtraction of a datetime
and a timedelta giving a datetime.
Representation: (days, seconds, microseconds). Why? Because I
felt like it.
