#2219: Basic array-like function like sin; cos ... are too slow with numpy-MKL

 If we perform a sin function on a very big array the computation is very
 slow respect to the real possibility offered by MKL.

 Example:

 {{{
 x = np.random.rand(1e7)
 y = np.sin(x) # is too slow !!! and it's not parallel!
 }}}

 I've seen that mkl offers the functions for solving these operation in a
 performant manner.

 Can you implement these functions in munpy in a better way?
