Moved preconfigured students into dedicated module
Handshake activity and supporting student methods
Handshake lengths governed by behavior.
A couple of renames.
Student class cleanup
Fixed error: study period behavior rename was not picked up
Improved study loop
Added prepare phase for all activities.
Merged Handshake activity into StudentInteractionActivity + renamed latter to PeerStudentInteractionActivity
Stateless activity execution + minor fixes
Student register and PerrInteractin invocation (incomplete, broken)
Fixed requirements.txt again
* Simplified activities - turned into "scripts" on student, instantiated ("planned") by the student itself.
* Removed student register - it's not used now
* Removed PeerStudent InteractionActibity implementation - it was designed to model synchronous interaction,  while asynchronous interaction is simpler to imlement and way more common
Student messaging and simplified student acquaintance
Message processing for student
PeerStudentInteractionActivity implementation
Behavior for sending messages
Preconfigured students refactoring
Expanded trace.log size + reconfigured initial students
Implemented student interaction
Resources roster and resource exchange
Fixed tests, commented out study test - it's way to different from current implementation
Moved resource access check from simulation to resource.
Students keep roster of known resources
