Created libMolecuilderLinearAlgebra.

  • is shared.
  • contains the following classes: Line, Plane, Space, Vector, Matrix, gslvector, gslmatrix, linearsystemofequations
  • had to change include path almost everywhere
  • change linkin in src/ and src/unittests/Makefile.am
  • Property mode set to 100644
