Moved the filter class to the bottom of the file, added a doc block, added a function to set, globalize, and return the filter, and replaced a call to create a filter class object with a call to the new function.
Created a form helper class and updated the form function so it uses the helper class to set the taxonomy term select options for days and types.
Added the filter object into the mix for the small groups search results but it's not yet being used to filter results.
Removed commented-out console.log call and intendented a line.
Removed all references to the fieldset theme, made efficiency-related updates to the filter class and updated the filter form function to make it simpler to maintain.
Deleted the fieldset theme template file.
Removed map div when no results are found; updated the join for the location_instance table so it joins on the node revision id rather than node id; added filtering of search results by submitted form values; added sorting by distance when a zip code is provided.
Fixed the  logic and the field wrapper div ID assignment.
