Creation of the Polynomials module with the following features:
...
* convenient functions:
- Horner and stabilized Horner evaluation
- polynomial coefficients from a set of given roots
- Cauchy bounds
* a QR based polynomial solver

Move documentation of MatrixBase methods in MatrixFunctions to module page.
...
I think that because MatrixFunctions is in unsupported/ and MatrixBase is
not, doxygen does not include the MatrixBase methods defined and documented
in the MatrixFunctions module with the other MatrixBase methods. This is a
kludge, but at least the documentation is not lost.

matrix_function test: replace expm(A).inverse() by expm(-A)

The latter is more stable. This fixes one of the issues with the test.
Also, make typedef's in MatrixFunctionReturnValue public; this is
necessary to get the test to compile.
