shift register values

[developer001]

I forgot to mention that I want the 2d array to be built horizontally, instead of vertically. SO the extra tranpose is in their for this reason.

Sorry for the confusin, I removed the extra stuff. The new version should be better!

And the shift register with the 1D array is for keeping track of all the mean values. I forgot to put in a build array (but you can ignore that for now!)

Do NOT append columns to a 2D array. Always append rows! You can always transpose for display purposes.
