Description
TMapPoint is a class for working with Latitude/Longitude points.
It includes constructors that take coordinates as (DD:MM:SS.sss)
or (DD.ddd). Does point to point great circle range & bearing,
as well as finds a point at a range & bearing.
I use this class for radio path length calculations to the
horizon & searching for radio interference. Never tried flying
Vancouver to Heathrow with the figures. (NO. I'm not a pilot).

In version3 I've added a constructor that takes input as a pair
of char* 's. Can be in the form DDD/MM/SS.sss or DDD.ddd .
This makes the use with keyboard or AnsiString.c_str()
entry a lot eaisier as the constructor handles the parsing.
An exception is thrown if the constructor gets confused.
See the comment for the constructor taking char* as an arg.

Good luck with it.
Drew.
