WIP: Step 1 of redesign of quadrature rules
requested to merge simon.praetorius/dune-geometry:feature/redesign-quadrature-rules-step1 into master
Summary
All quadrature rules are moved to subdirectory quadraturerules, with a common filename scheme. The whole implementation for each rule is now put into one file. Therefore, the .mac scripts are adopted to generate these file structure directly.
Motivation
This is the first step of a cleanup and redesign of the quadrature rules: 1.) put all rules into a similar structure. 2.) cleanup of the classes QuadratureRules and QuadratureFactory, 3.) Automatically generate coefficients for all rules with higher precision
