    execute triggers
    loads engines
  
!   parseTree()
!     takes a GObj based object tree and creates a GTrigObj based tree from it
!     the GTrigObj's are defined in individual applications along with a cross 
!     reference to their GObj counterparts
! 
!     it extracts each defined trigger and creates trigger object
!     it inits the needed triggerEngine
! 
!   executeTrigger()
!     executes the requested trigger when given the name

+   it hides the individual language engines

  trigger
    stores source and lang type
    stores compiled version (compiled by the engine)
+   contains a state, list of arguments, output value
+   passed into the engine when being processed
+     when exits from engine the state can be checked 
+     to verify trigger completed successfully
