User @mention Notification
Forward @username mentions to another channel
Ever get pinged because your @username was mentioned in a chat room? This Function will get you started with that same flow. It parses all messages that travel through the channel. If that message has a @username mention in it, it forwards the message to the @username channel.

Walkthrough
Any message sent over your channel will be parsed for the @username using a regular expression. If @username is detected, the same message is forwarded to the @username channel. The original message still reaches the intended target.
In production every user should have their own @username channel that is locked down with PubNub PAM so only they can access it.
Input
A message is published on the input channel: user-mention-channel
1
Output
Note that the message is identical, but the new message has been duplicated and sent to a channel called @username.
