Class Overview
A singleton class that facilitates communication between other Espresso instance that may be running in different processes.
This class depends on InstrumentationConnection to notify about the discovery of other
remote Espresso instances and provide their Messenger object to use for further IPC.
To get the instance of this object getInstance() should be called. The user of this
class should then call init() prior to attempting to use any functionality of this
class. Call terminate() after using EspressoRemote to release any resources. Failure to
do so will lead to memory leaks and unexpected behavior.
