Created a search-menu template and corresponding controller.
Moved functions out of SearchController to SearchMenuController.
The two controllers share information through ngModel.
The search menu now opens to having none of the types
checked, but 'ALL' checked. Checking anything besides
'ALL' unchecks 'ALL' and begins filtering search by
type.
Clicking on names of options in the search
menu will now toggle the checkboxes. The
filter options display now says when no
filters are selected. Slightly moved the
search menu to the left.
Make the 'Load more' button work with the
new filtered results. Added 'ALL' to the top
of the search menu which allows the user to
toggle all of the filtering options easily.
Changed the controller to update the tree
display status when the search result
promise is fufilled, not before making the
search query.
Also chagned the loading increment from
5 to 20.
The controller's loadMore function now sends
new queries to the search service if the
controller's full results list does not have
enough results in it to load more.
