Initial work on fixed-point functions and OSVR Hacker Dev Kit driver.
OSVR Hacker Dev Kit driver successfully compiles now. Added basic fixed-point class.
Added the vrpn_Tracker_OSVRHackerDevKit to the setup registry.
Namespace and format the HDK and fixed point code.
Explicit constructors for fixed point.
Use an explicit "get" member, instead of conversion operators, to extract data from fixed point.
Comment tweaks
