//DESCRIPTION
This script takes a folder with an ordered sequence of images and  assembles them into a single image based on the specified number of 
columns. If the number of columns is left empty, the sequence will be assembled into a perfect square. 

//INSTALLATION
Copy the script into the Scripts folder (.../Photoshop*/Presets/Scripts). Restart photoshop for the name of the script to appear in the Scripts menu. Scripts added to the Scripts folder while Photoshop is running will not appear in the Scripts menu until the next time you launch the application. 

//RUNNING

or
-Double click the script file from its current location

//TESTING
