FEATURE: Implement Search Bar Functionality

This implements a search bar that with meteor-easy-search https://github.com/matteodem/meteor-easy-search/

Displays the card template for the users above the current selection. Easy search allows for a lot of flexibility in terms of template reactivity 
when a search occurs. Search counts, finding out if a user is currently searching or finished are included.

I could not find a way to style the searchbar in the way I wanted to easily, and it also uses a regular text box instead of a search box (so you miss -webkit features like the (x) button in the searchbar. However, this is a good first pass that implements search functionality across the `full_name` attribute of the NflPlayers collection.

-Implements `meteor-easy-search` for searching across Collections in Mongo (ElasticSearch is supported in the future)
-Renders template of search results to the area of the cardlist (above the other filtered selection of cardlist results)
-Small divider between search results and cardlist results
