eig of a matrix of BigFloat's causes an infinite recursion:

julia> eig(convert(Matrix{BigFloat},randn(2,2)))
ERROR: stack overflow
 in eigfact! at linalg/factorization.jl:501 (repeats 80000 times)

Partial dup of #11 (although it should presumably give a MethodError, not a stack overflow).

Infinite recursion is the correct error given this definition, since the specific method for BigFloat does not exist.

eigfact!(A::StridedMatrix) = eigfact!(float(A))

@ViralBShah, I agree that Julia is doing what we tell it to do, but I don't think this is what we want it to do. We should throw a MethodError if eigfact! is called for unsupported numeric types.

Bump for eigvals.
How about using mplapack as backend?
