Adding/changing names of stations 

Cleanup

Adding extern on clang is an error:
ogs/MathLib/Integration/GaussLegendre.h:32:17: error: expected unqualified-id
    extern template <> double const GaussLegendre<1>::X[1];

This avoids unnecessary copy initialization
and value parameters.

Also remove unneeded default dtors.

It is defined multiple times through different translation
units.

Those warnings are showing with a newer clang-3.9
compiler.

Updating Schema paths

Explicitly instantiate shape matrices

Remove Global Mat/Vec from template parameters

add missing dependency for dynamic linking

Make MeshSurfaceExtraction independent from GeoLib

- range-based for loop
- std::make_pair instead of std::pair<T1,T2>
