fixed framework.json (missing [ before a 'children' key)
making progress on extending nestedlist to store selection states
Selections in FilterDetailList now persist while navigating different branches. TODO: populate filter input box with selections in list, add control function for altering FilterDetailList depth based on filter tier field. Add code for applying filters to dataset
filterDetailList can now show and hide using 'Done' button. Still need to move selections from list into the form and then filter the data.
