				<div class="class-description"><p>Abstract base class of interpolants over parametric samples.</p>
<p>The parameter domain is one dimensional, typically the time or a path
along a curve defined by the data.</p>
<p>The sample values can have any dimensionality and derived classes may
apply special interpretations to the data.</p>
<p>This class provides the interval seek in a Template Method, deferring
the actual interpolation to derived classes.</p>
<p>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.</p>
