get a dimension from an element type
support non-square elements in regular mesh generation
support non-square elements in generateStructuredMesh tool
fix clang warnings
indent by one tab to align the parameters
move getElementDimension() to generateStructuredMesh.cpp
[AL] Add back addToGlobal() in VectorMatrixAsm.
[T] Add GlobalMatrix/Vector to SteadyDiffusion2D example.
Merge pull request #494 from norihiro-w/support-lxly-quad-meshing

Support non-square elements in regular quad mesh generation
[A] Reorder command line argument.
[A] Return 0 at end of the programm.
[A] Move loops together.
[A] Add version info.
[A] Clarify help for element types.
[A] Whitespace.
[PL] GW: Add LocalAssemblerData skeleton.
[PL] GW: Fill init, assemble. Add shape matrices.
[AL] Add LocalDataInitializer.

This adds a mapping from element types to the
corresponding shape functions. The latter are
passed as a template parameter to the
LocalAssemblerData.
[PL] GW: Store hydraulic conductivity in each elem.

This shall be changed later to incorporate different
material properties.
[PL] GW: Rename LocalAssemblerDataBase to Interface.

Same change in the AssemblerLib for consistency.
