These changes address two JIRA issues:
- 291 unittest reported leaked objects
- 292 SHAMap::treeNodeCache should be a dependency injection
The treeNodeCache was a static member of SHAMap. It's now a
non-static member of the Application accessed through
getTreeNodeCache(). That addressed JIRA 291
The SHAMap constructors were adjusted so the treeNodeCache is
passed in to the constructor. That addresses JIRA 292, It required
that any code constructing a SHAMap needed to be edited to pass
the new parameter to the constructed SHAMap.
In the mean time, SHAMap was examined for dead/unused code and
interfaces that could be made private. Dead and unused interfaces
were removed and methods that could be private were made private.
* Rename unity files
* Move some modules to new subdirectories
* Remove obsolete Visual Studio project files
* Remove obsolete coding style and TODO list
