* Abstract base class of interpolants over parametric samples.

* The parameter domain is one dimensional, typically the time or a path

* The sample values can have any dimensionality and derived classes may
* apply special interpretations to the data.
*
* This class provides the interval seek in a Template Method, deferring
* the actual interpolation to derived classes.
*
* Time complexity is O(1) for linear access crossing at most two points

* - You can also add and remove objects later when the mixer
