- Doxy-fied the rest of the SortingAndSearching
- Doxy-fied the 234Tree

SortingAndSearching Changes
	- Minor tweaks to previous improvements (not anything really important)
	- Converted to cmake

234Tree
	- Finished work on Doxygen
	- Converted to cmake and added code to it so that it works with both cgraph and graph
	- Cleaned up a few redundant includes and a couple of unnecessary code lines

* Still need to intergrate the doxygen output to the cmake (coming up ...)
* A couple of tweaks need to be made to the insert function of the Tree class (some time in the distant future)
