 Note to moderators / anyone interested:
 =====

 The following libraries are served off of a well-known provider of Javascript 
 libraries called [cdnjs][1], which happens to be in your whitelist of usable
 CDNs.

 I have refrained from using @require in the script manifest in order to fully 
 support Google Chrome, a browser used by more than half of Internet users [(StatCounter Oct 2014)][2]. 
 This is a [known issue][3] which means that @require support has been willingly
 left out of Chrome. I hope that this is more than enough reasons to 'break' the
 rules of having to use @require.
