This commit has its date moved to earlier to reflect when the work was completed, as I forgot to actually make the commit until 2 minutes after midnight :/. It partially fixed a bug where ADT requires equality for its member types but won't use templated equality to be if there isn't a regular equality operator (not templated) it always returns false
