Changed TYPED_TEST_CASE to TYPED_TEST_SUITE, as per google test recommendation which said that TYPED_TEST_CASE is deprecated.

This is necessary to be able to run tests in parallel.

Added Type instead of all int indexes. Formatted includes to top of file. Removed the need for using namespaces.

Added template testing for all working tests. Implemented RealTypes and occasionally IndexType instead of int/float/etc. Updated TODO.

	Added getType test error location, commented out its tests.
	Added visual representation of used matrices in tests.
	Added working and correct version of addElement test.
	Fixed vectorProduct test for Host, CUDA throws illegal memory
access.
	Fixed performSORIteration for Host, CUDA throws segmentation
fault.
	Fixed load/save test to not use a path.
	Added test for print function.
	Reformatted code.
	Added messages thrown for CUDA errors into tests, so that the
whole test doesn't crash after those errors.
	Updated TODO.

Added another approach using Vector.h for test of vectorProduct function. Added a concept test of performSORIteration function. Added test for save and load functions. Updated TODO.

Adding commented-out, provisional and non-functioning test for vectorProduct function. Adding only for backup purposes.

Added format dependent test for the setElement function. This is format dependent, because setElement won't work without setting rowLengths.
