Added hash functions (not secure just for use in hash maps)
Added cube OBJ asset file
Added CMakeLists.txt file for the crypto module
Added assignment from string and char*,
refactored check for size==0 to .empty()
Changed append function so that it returns the new path now
Added member functions for accessing array sizes and assigning paths
Added material library and material importer classes
Added a solution to the "where is the testpath" problem in Visual Studio 2012:
The path to the test files is now hard coded and written during execution
of the CMake configuration and made available through a global variable.
This avoids trouble with different testing environmnents.
Added a new class: HashMap for unordered storage.
Similar to tr1::unordererd_map
Added new tests for the filesystem module
Added new tests for the import module which tries to load an OBJ file
Added files and some tests for the storage module testing hash map functionality
Now using ObjModel with ObjGroup sub-objects
Added several submodules
Added environment variable for test environment.
However this sometimes does not seem to work, for instance with the
googletest-addin for VS2012 the environment variables are not accessible from the test code.
