Greasy Fork

• removed @grants that were no longer used
• clarified metadata required by scripts using this library

• simplified the import, avoiding pointless CSP hurdles

• deleted unworkable scheme for storing class
• added more info to the intro section

• attempted fix for retrieving Denque class

• removed a spurious @grant
• removed package version suffix from the key that stores the exported class, so that fixing the packaging doesn't break scripts

Still getting homepage together

just polishing the script page
