Detailed Description

class Dt1DTableFn:

Dt1DTableFn holds a 1D table function. The data is represented in arbitrary increments. Methods are provided for looking up linearly interpolated values and integrating over a specified range. The time for a table lookup grows like log(n), where n is the number of data points.
