Refactored JS code, moved api calls over to php script, urlencoding multi-word searches, resizing images
updated readme, using SSL for requests and auth
Moved api credentials out into xml file, updated functions to use xml,
updated prediction json body, proper closing of curl connections
put server name into variable
