[eigen] OCaml numerical library and bindings

[Pavan Maddamsetti <pavan.maddamsetti@xxxxxxxxx>]

Hi,

I don't have write access to the wiki but thought it might be relevant to add the following links under "Projects using Eigen":

'''Extensions, numerical computation'''

* {{Owl|https://github.com/ryanrhymes/owl}} is an OCaml numerical library: dense and sparse matrix, linear algebra, regressions, maths and stats functions.

'''Bindings'''

* {{Eigen|https://github.com/ryanrhymes/eigen}}, a thin OCaml interface to the Eigen 3 C++ library.

Thanks.
