/************************************************************
* AP_mount -- library to control a 2 or 3 axis mount. *
* *
* Author: Joe Holdsworth; *
* Ritchie Wilson; *
* Amilcar Lucas; *
* Gregory Fletcher; *
* heavily modified by Randy Mackay *
* *
* Purpose: Move a 2 or 3 axis mount attached to vehicle, *
* Used for mount to track targets or stabilise *
* camera plus other modes. *
* *
* Usage: Use in main code to control mounts attached to *
* vehicle. *
* *
* Comments: All angles in degrees, distances in meters *
* unless otherwise stated. *
