Added search div and partial with necessary tags to index page
We approached index page improperly. Should have been projects index listed by category but is vice versa. I moved the projects format into a project partial and putin projects views.
Tag search is working with html format
Ajaxified tag search up and running
Fixed ajax so that it would call more than the first time
Turned off button when on clieck and back on when ajax request is done.
Made ajax search function and put into application js in order to use only one document ready function and have all event listeners in one place
Made a few house keeping changes.
