Function split 

pub fn split<T: Element>(
    a: &Array<T, IxDyn>,
    n_sections: usize,
    axis: usize,
) -> FerrayResult<Vec<Array<T, IxDyn>>>

Split an array into equal-sized sub-arrays.

n_sections must evenly divide the size along axis.

Analogous to numpy.split().

Errors

Returns FerrayError::InvalidValue if the axis cannot be evenly split.
