Add a table identifying the TIFF test files

Currently, the Commons Imaging distribution includes a number of test files used for running TIFF unit and integration tests. The TIFF format supports a very wide assortment of file configurations, so there are quite a few test files. 

I have submitted a pull request that includes example application that surveys the test files and tabulates a list of the various file names and associated TIFF configurations.  I also bundled the table (in the form a a simple text file and a CSV) with the test resources in the Commons Imaging distribution.

A copy of the test file is attached
