see http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.var.html#numpy.ndarray.var

There is already an implementation in https://github.com/lensacom/sparkit-learn/blob/master/splearn/feature_selection/variance_threshold.py#L62 but it should use ndarray.var instead of mean_variance_axis.
