Simplifying routing a bit helps me to check which endpoint the user is
visiting. Also will make it a lot easier down the road to rewrite,
whenever I get around to renaming "autocomplete" to a more appropriate
name (like "suggestion" or something).
Basic autocomplete/search suggestion functionality added
* Adds new GET and POST routes for '/autocomplete' that accept a string query and returns an array of suggestions
* Adds new autoscript.js file for handling queries on the main page and results view
* Updated requests class to include autocomplete method
* Updated opensearch template to handle search suggestions
* Added header template to allow for autocomplete on results view
* Updated readme to mention autocomplete feature
