matched the quad order in the maxima scripts to the definitions in quadraturerules.hh, final cleanup, tested everything

refactored the writequad maxima script, it produces (apart from comments) the same files as before for jacobi rules and gauss lobatto rules

Guard against misuse of AxisAlignedCubeGeometry constructor

See merge request !150

The AxisAlignedCubeGeometry has always had a constructor that was always
intended to be used with dim==coorddim only.  However, this precondition
was never checked anywhere, which could lead to strange bugs.
This patch introduces a static_assert that fails at compile time
if the dim==coorddim precondition is not met.

BUG: core/dune-geometry#25

[axisalignedcubegeometry] Remove copy assignment operator

See merge request !149

* operator does the same as the default-generated one
* fixes compiler warning

Fetch default yml files via different project instead of url

See merge request !147

This is a workaround for a bug that showed up after gitlab migration. See issue
infrastructure/issues0#62 for further discussion.

ref:core/dune-geometry\> This MR adds using directives for the use of

Dune are probably found before the names in the namespace std.
