mp_integer: a couple more notes for future improvements.
real: a couple of todo items.
Add a new performance test.
g4 test: minor cleanup.
mp_rational: first bits for the equality operator.
A couple of syntax changes in inheriting constructors and initial files for Intel
compiler support.
More infrastructure support for the Intel compiler.
type_traits: workarounds Intel compiler bugs.
Another couple of style changes for inheriting ctors.
Disable the tests the cause ICEs in the Intel compiler.
base_term: some style/doc improvements, and change the way we do SFINAE
on the generic ctor. This is the form we have been using lately and
the Intel compiler seems to work much better with it.
mp_integer: in the tests, make sure we are comparing integrals with the same
signedness.

This should fix #7.
