ENH: rateOfChange function for interpolationTable.

Browse Source 
Creates linear slope only from low and high elements around the sample
value, so rate will be discontinuous.  Would be better with higher
order gradient calculation.

Description
An interpolation/look-up table of scalar vs <Type> values.
The reference scalar values must be positive and monotonically increasing.
The reference scalar values must be monotonically increasing.
The handling of out-of-bounds values depends on the current setting
of @a outOfBounds.
