Function to set whether this is a time-dependent function or not.
This is intended to be only used by subclasses who cannot natively determine time-dependence. In such a case, this function should be used immediately following construction.

Const pointer to our master, initialized to nullptr
.
There may be cases where multiple functions are required, but to save memory, one master handles some centralized data.
