Inter and Intra Snap communication

Hi Jenny,

Here's a link to the documentation showing how to include more than one
executable in your snap package, as Sergio and Gustavo already mentioned:

In it you will see that the apps: stanza can have multiple children, one
for each executable you want to expose outside of your snap. These will
take the form of /snap/bin/<snap>.<app> and can be called from the
command-line. If <snap> == <app> it will condense down to just
/snap/bin/<snap> to be cleaner.
