/**
 * The openSession() method starts the OTR protocol.  It creates a BasicChan object
 * that is passed into OtrSendAlice and when the key exchange is complete, this Chan
 * "chan" is notified and an OtrSession object is returned.  We also create a SessionImpl
 * object for handling messages and pass that into both our OtrSendAlice object and the
 * returned OtrSession object.  To start the actual protocol, a specific string needs to
 * be crafted.  In our implementation, we used "?OTRv23?" which means we are initializing
 * OTR version 3, with version 2 as a backup if version 3 is not available.  Other protocol
 * strings are possible.  We then call chan.receive(), and when the key exchange in
 * OtrSendAlice returns, we check to see if the key exchange was successful or not.
 * If it is, we return a new OtrSession object.  Else, we shut everything down.
 *
 * Note: The OtrPolicy variable allows OTRv2 and OTRv3.  This can be changed if the user
 * desires different versions of OTR.
