* Abstract base class of interpolants over parametric samples.
*
* The parameter domain is one dimensional, typically the time or a path
* along a curve defined by the data.
*
* 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
* and O(log N) for random access, where N is the number of positions.
