551368 Filter Functionality on Trademark Search Results Page

Implement filtering functionality (on market and class) on our currently-existing trademark search results page. For filtering, there should be some sort of pop-up with checkboxes (or other filtering mechanism) to select/deselect parameters. The appearance of the filters should largely be based on [login to view URL], including being in the adjacent column, but we are open to suggestion (such as under the search box). All parameters should be activated by default.
