Example program for dorcsd

This example finds the full CS decomposition of
X = -0.7576 0.3697 0.3838 0.2126 -0.3112 -0.4077 -0.1552 -0.1129 0.2676 0.8517 -0.0488 0.7240 -0.6730 -0.1301 0.0602 -0.2287 0.0088 0.2235 -0.9235 0.2120 0.4530 0.5612 0.5806 0.1162 0.3595  
partitioned so that the top left block is 3 by 2.
The decomposition is performed both on submatrices of the orthogonal matrix X and on separated partition matrices. Code is also provided to perform a recombining check if required.
