Longley Rice propagation model - Public Domain

* The following code was derived from public domain ITM code available *
* at ftp://flattop.its.bldrdoc.gov/itm/ITMDLL.cpp that was released on *
* June 26, 2007. It was modified to remove Microsoft Windows "dll-isms", *
* redundant and unnecessary #includes, redundant and unnecessary { }'s, *
* to initialize uninitialized variables, type cast some variables, *
* re-format the code for easier reading, and to replace pow() function *
* calls with explicit multiplications wherever possible to increase *
* execution speed and improve computational accuracy. *
