This ticket implements two inhomogeneous bases of the symmetric functions, one called the `irreducible_character` and the other `induced_trivial_character` and shorthands `st` and `ht`. These bases play the roll for the symmetric group realized as permutation matrices that the Schur functions play to the character of the irreducible Gl_n representations. In addition, two methods are added to the symmetric function element class. One `eval_at_permutation_roots` that evaluates a symmetric function at the roots of unity of a permutation matrix with a given cycle type and the other, `character_to_frobenius_image`, interprets a symmetric function as a symmetric group character and computes the Frobenius image.

Several packages need C++11: * pynac (#19312) * Givaro + Linbox + FFLASFFPACK (#17635) * cryptominisat (#15674) They need different subsets of C++11. The first full featured C++11 gcc version is 4.8.1. The version shipped with Sage at the moment is 4.9.2. This ticket should implement install/usage of Sage's gcc if the native gcc version is less than 4.8.1. The resp. package tickets will depend on this ticket and activate the C++11 switch in their compile process.

Here is the semigroup algebra (over `QQ`) of the semigroup with two elements whose product is given by `x*y == y`: {{{ sage: A = FiniteDimensionalAlgebra(QQ, [Matrix([[1,0],[1,0]]), Matrix([[0,1],[0,1]])]) sage: for x in A.basis(): for y in A.basis(): print x*y == y ....: True True True True }}} Sage claims that it is unitary: {{{ sage: A.is_unitary() True }}} based on the following wrong concept: {{{ .. NOTE:: If a finitedimensional algebra over a field admits a left identity, then this is the unique left identity, and it is also a right identity. }}} On a slightly related note, the `table` method on `FiniteDimensionalAlgebra` returns mutable matrices, and mutating them corrupts the algebra.
