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

	Added TODOs to implement rowPointer test for
setCompressedRowLengths and setDimensions test functions.

assuming that getRowLength() works correctly and doesn't need to be
tested.

Added test for setDimensions function. This test is correct assuming that getRows() and getColumns() work correctly and don't need to be tested.

Divided testGetType into separate functions, one for Host and one for CUDA, to avoid non-CUDA systems having difficulties.

	Was using EXPECT_STREQ, instead of EXPECT_EQ.

	Create the testGetType and its corresponding gtest.

Edited formatting in SparseMatrxTest.h

	Initial import of .cpp .cu .h files for the new test.
