ENH: support frequency or period for Sine/Square Function1 (#1917)

Browse Source 
- For slow oscillations it can be more intuitive to specify the
  period.

ENH: separate mark/space for Square

- makes it easier to tailor the desired intervals.

BUG: incorrect square wave fraction with negative phase shifts

ENH: additional cosine Function1

STYLE: avoid code duplication by inheriting Cosine/Square from Sine.
