Agent class
=================================================================

This class is the base class for all AgentXXX classes (AgentSST, AgentScheduler, AgentImagesProcessor...)

It runs an infinite loop (called main_loop) doing at each iteration
some routine tasks (process_routine before and after)
and executing commands sent by other agents.

To start it up, from the project root :

- In normal mode :
- ./PYROS start -fg agent -o tnc
(add -d after the PYROS command for debug mode)

- In test mode (the agent will execute a scenario 
as a suite of commands (in TEST_COMMANDS_LIST) 
to send to himself (or other agents) 
and execute them on reception at each iteration :
- ./PYROS -t start -fg agent -o tnc
