Tweaked visuals. Added a tutorial/instructions screen to displayed upon first search. Removed some redundant/unused code. Made images display differently: rather than altering the 'current-image' class between different img tags, images are now displayed as the background of a single div. Fixed bug with minimap not centering properly on customized routes. Made SVG grab more images by using the route legs and steps, rather than using overview_path. Made minimap marker a single marker than moves around, rather than constantly creating and destroying markers.
Duplicated code to new folder.
