function Y = mirrorImage(X)
% mirrorImage  do X upside down.
% reverses the direction of the given image
%
% Inputs:
% * X ... uint8 nxm matrix (n,m>1)
%
% Outputs:
% * Y ... uint8 nxm matrix up side down
%
% Example
% Given is an uint8 image matrix (which was loaded with imread), with 
% |Y = mirrorImage(X)| you get the image upside down.
%
