Implemented CollOfScalar > Scalar and CollOfScalar < CollOfScalar
Added support for Array Of X Collection Of Scalar
Added tests for Array of CollOfScalar.
Implemented CollOfScalar < Scalar
Added CollOfVector::col as it is used by the front-end output. Col took the implementation of operator[], and operator[i] now returns col(i)
swe compiled and run with the CUDA back-end. Correct results with dam break 1D test case.
