changes in GeoLib and in SimpleTests folder results from changing the namespace

in order to make the name of libraries, namespaces and directories more consistent the Base directory is know named BaseLib

special conds for windows setup integrated - path for metis and inclusion of winmm.lib for time measurements

implemented new class CRSMatrixReorderedOpenMP which uses Nested Dissection reordering and OpenMP for matrix vector multiplication

fixed a small issue concerning compiling with OpenMP support

added more documentation to quicksort
added class CRSMatrixReordered
first version of nested dissection based on metis is now working

Wrapped OpenMP includes in #ifdefs.

fixed a warning in amuxCRS concerning an unused parameter
