Because BasicGeometry doesn't actually use it anymore.

For the time being, dimG remains a template parameter of the
DefaultGeometryTraits class.  This is for backward-compatibility
only.  The template parameter gets ignored completely.

T must be default-constructable, copy-constructable, and assignable.

This reduces gcc's memory demand further (aroung 0.5G) when compiling
ReferenceElements< double, 8 >.

[[Imported from SVN: r204]]

This allows compiling the ReferenceElement< double, 8 > with gcc using less than
1G of memory.
Unfortunately, memory at run time will still be nearly 2G (just for the reference
elements).

This will become the replacement for the hybridmappings in the reference elements.

* derive the tolerance from the machine epsilon

[[Imported from SVN: r194]]

Within the reference elements, the ReferenceDomain is only used to set up the
mappings, now.
