> ---Efficient Queue---
> 1. Change AbstractWorkingMemory.actionQueue to LinkedList and use the
> Queue interface.
> 2. AbstractWorkingMemory.executeQueuedActions change it to get the item
> from the queue - rather than the current list.remove( 0 ) which is
> causing a lot of array copies in the ArrayList.
> ---Stop Re-entrant queue evaluation---
> 1. Add boolean evaluatingActionQueue.
> 2. Have the AbstractWorkingMemory.executeQueuedActions method check if
> true, if so then return - i.e. don't evaluate the queue, as we are
> already iterating it.
> 3. If not set to true and iterate the queue until empty, before
> executing set back to false.
