Option to Exclude Geometry from Hash Key

Testing has revealed that the automatic inclusion of geometry in the hash key is preventing the tool from producing the desired results in comparisons where a hash key is required.

Please add an option to the tool to exclude geometry from the hash key. Thank you!

Start by locating the hash-key generation and the option or configuration entry point used during comparisons. Add a user-selectable way to exclude geometry while preserving the current default behavior, then verify that comparisons requiring a hash key produce the expected results.
