Detailed Description

Acoustic Impedance model.

Input must be depth sorted. A point indicates the start of a layer. Everything above the first point has the properties of the first point. The first point's depth and velocity determine the output start time.

The input arrays are const T* for ease of cross-use. Don't pass nulls though, users will be disappointed with the resulting crash. Similarly: don't give crazy values like vel or den <= 0. No checks for Undefs.

Additionally: (1) Everything must be in SI units, no ft, ft/s, g/cm3 or other trash. (2) Velocity is one-way (i.e. a rock property). (3) Time is in seconds.
