Bulk Mac local user creation

This utility takes in a source CSV file, parses it, and creates users out of the contents.

Note : this script has not been updated for LDAP user creation yet. You can call the -L option without effect.
Note : the users RealName cannot contain spaces. (Parsing counts array objects as double).
Note : scripted on and for Mac OS X 10.9, haven't tried any other OS X version yet.

-h for help!
