description:
Bugfix in TensorElement.extract_component.

Added simplified default symmetry for second order tensor elements:

element = TensorElement("CG", polygon, 1, symmetry=True)

will yield the most used symmetric second order tensor (matrix)
element that occurs in so many physical applications.

The symmetry argument should be well documented,
it's definitely not obvious what it means.
