The porting to gonum/matrix has been done but not tested. The purego option is surely broken
Added SetMatrix function to gonum.go. The library is broken at this point
Fixed most issues including the implementation of the View() method of VecMatrix. The library compiles but it does not pass the tests. I get a panic in an apparently corect gonum function. I suspect the bug is in the gonum side. The purego version is broken
Gonum version fails at TestWaters. Pure Go version implemented in gonum_purego.go, it fails at TestSuper. Bor both,  outputs have been checked unitl TestPutInXYPlane
A bunch of bugfixes
Gonum implementation working until TestReduce.
gonum implementation passess the tests
gonum based and purego pass the tests
ChemDense is now chemDense, so is not exported
