fixed issue with the grid path adding loops
added overclock param - for calling the planner thread more frequently
added support in the header for overclocking the planner thread and new goal handling
added over clocking and better handling of new goals
removed prints
fixed issue that was not calling the planner ocassionally - and also added logic for the planner to be called immediately when the controller gives an error
wrote new gradient based function which seems more stable with the A* expansion which doesn't have enough potentials for gradient calculations
removed old function from the header
changed path set to use int (with precision)
added a backup path extractor when we use the gradient - so that we dont return failure

changed to allow the move base the option to call the planner immediately - by default it will wait till the planner thread is called at the defined frequency - only relavent if we are over clocking
