* Modified the Ng_GetElement_2D function to return also the element type giving it the same base functionality as Ng_GetSurfaceElement, but with the capability of returning the region index too (called matnum)
* Added the capability of generating Second Order 2D / 3D Meshes in Nglib
* More Meshing Parameters now taken into account in Nglib
* Streamlined the process of transferring the locally defined meshing parameters to the internal meshing parameters structure using a single function called "Transfer_Parameters"
* Formatting changes to make the gaps between function definitions consistent
* Added a new compile target for Nglib (Release(OCC))
* Netgen and Nglib solution files updated to remove non-existent files and add new source files into project
* Implemented by adding a dllexport / dllimport header for all exported functions to indicate to windows which functions are to be made available via the library.
* System change driven via WIN32 define, making it transparent to Linux builds.
