/**
* This command "starts a turn" (in Chamilo language, makes a session available)
* for all its users (they need to already be subscribed to the session)
*
* Assumptions:
* - the session exists but has start and end date previous to the real exam date
* - the session is made available simply by making the start and end date period so large that there's no chance it wouldn't work
* - users need to be subscribed to the session already
* - the context must be very limited: the turn is defined by the display_order field in the branch_rel_session table. The value of display_order must be unique in this table (you cannot have more than one branch with sessions)
