cea3bdc8e5 Fix Cholesky::determinant for Complex elements 
The previous implementation was correct only for real elements. The
Cholesky decomposition is `L L^H`, so the determinant is `det(L) *
det(L^H)`. Since `L` is a triangular matrix, `det(L)` is the product
of the diagonal elements of `L`. Since `L^H` is triangular and its
diagonal elements are the conjugates of the diagonal elements of `L`,
`det(L^H)` is the conjugate of `det(L)`. So, the overall determinant
is the product of the diagonal elements of `L` times its conjugate.

cbef37ed9c Fix proptest functionality test 
The previous test claimed to verify that all possible outputs
are sampled, but it didn't. This commits fixes this issue
by actually computing all possible combinations.
However, to accomplish this we needed to add itertools as a test
dependency. Otherwise we'd have to implement our own way of
generating the Cartesian product of an arbitrary number
of sets.

f9ea2b4471 Initial proptest implementation for nalgebra 
This introduces functionality for creating strategies for matrices and
vectors, as well as an implementation of Arbitrary.

Strategies for the geometric types (Point3, Quaternion etc.) are not
currently part of this contribution.

The current strategy implementation for matrices has some limitations
that lead to suboptimal shrinking behavior. This is documented in the
module-level docs, with some additional comments in the code.
