Excluding Regions

Using the 'config' flag and a simple JSON text file, it is easy to exclude regions of PDF pages from comparison.  This is commonly needed when there is information in the document that changes over time like date/time or version information.

Within the file, "rectangles" are defined that should be excluded from comparison.
