Masked Authenticated Messaging with mam.node.js wrapper.
The following code provides simple examples on how to broadcast data through the Tangle using MAM. In the examples folder you will find a file to send a message (publishPublicStart.js) and another to receive it by using the Root provided after the sending is done (fetchAsync.js). The code was taken from http://www.iotameetup.nl/2nd-iota-meetup-18-12-2017-amsterdam/ (Thanks Harm van den Brink!). Both files require minor edits as described on the comments
