I added a Deprecation warning with the correct function to use in numpy
(with alternative arguments) for the following:
    - mean
    - median
    - std
    - var
    - cov
    - corrcoeff
AFAICS, all functionality of any of those is available in numpy
(contrary to what the comment says, I guess they are vastly out of date),

cheers,

David
