- extends PicPipe
This pipeline gets a double and returns a double based on a piecewise linear function.
The function is formed by linear interpolation of a list of (x,y) pairs.
If the value exactly matches one or more x values, it takes the first one.
The (x,y) pairs should be sorted with increasing x values.
