What is claimed is: 1. A fuel control system for a mobile platform, comprising: a balancing fuel transfer circuit adapted to selectively transfer fuel between first and second fuel reservoirs, a crossfeed fuel balancing circuit for supplying fuel from a third fuel reservoir to two independent engines of the mobile platform, and for selectively transferring fuel from said third fuel reservoir to said first and second fuel reservoirs without interrupting fuel flows to said engines. 2. The fuel control system of claim 1, further including a controller for controlling said balancing fuel transfer circuit. 3. The fuel control system of claim 1, wherein said balancing fuel transfer circuit is further adapted to supply fuel to said engines from said first and second fuel reservoirs while simultaneously transferring fuel between said first and second reservoirs. 4. The fuel control system of claim 1, further including a control panel for selectively controlling the operation of said crossfeed fuel balancing circuit and said balancing fuel transfer circuit. 5. The fuel control system of claim 4, wherein said control panel further comprises: a first switch for enabling an operator to control a first fuel boost pump for pumping fuel from said first fuel reservoir to a first one of the engines; and a second switch for enabling an operator to control fuel flow from said second fuel reservoir to a second of the engines. 6. The fuel control system of claim 5, wherein said crossfeed fuel balancing circuit includes a cross feed flow control valve disposed within a fuel flow conduit in flow communication with said engines, for controlling a fuel flow between said first and second engines, and wherein said crossfeed flow control valve is controlled via a user activated control on said control panel. 7. A method for controlling a fuel system on a mobile platform having first, second and third independent fuel reservoirs, and a pair of engines, comprising: using a first fuel balancing circuit to selectively supply fuel directly to said engines from said first and second fuel reservoirs, and to selectively transfer fuel between said first and second fuel reservoirs to balance quantities of fuel in said first and second fuel reservoirs; and using a second fuel balancing circuit to supply fuel from said third fuel reservoir to said pair of engines, and to selectively transfer fuel from said third fuel reservoir to either of first and second fuel reservoirs to balance fuel levels in said first and second fuel reservoirs. 8. The method of claim 7, wherein using said second fuel balancing circuit further comprises simultaneously supplying fuel to both of said engines while selectively transferring fuel from said third fuel reservoir into one of said first and second fuel reservoirs. 9. The method of claim 7, wherein using a second fuel balancing circuit comprises using a pair of operator selectable pumps in communication with said third fuel reservoir. 10. The method of claim 9, wherein using a first fuel balancing circuit comprises using a crossfeed flow control valve in flow communication with both of said engines to control fuel flow between said engines. 11. The method of claim 7, wherein using a second fuel balancing circuit comprises using an operator controlled switch to initiate an automatic fuel rebalancing operation between said first and second fuel reservoirs. 12. The method of claim 11, wherein initiating an automatic fuel rebalancing operation comprises controlling a plurality of valves associated with each of said first and second fuel reservoirs to achieve fuel flow between said first and second fuel reservoirs such that a quantity of fuel in each of said first and second fuel reservoirs is approximately equal. 13. The method of claim 12, wherein fuel continues to be supplied from the one of said fuel reservoirs having a lesser amount of fuel than the other one of said fuel reservoirs, while the fuel reservoir with the lesser amount of fuel receives from the higher fuel reservoir. 14. The method of claim 7, wherein using said first fuel balancing circuit comprises using said first fuel balancing circuit to balance fuel levels in said first and second fuel reservoirs while said engines are not operating. 15. A method for controlling a fuel system on a mobile platform having first, second and third independent fuel reservoirs, and a pair of engines, comprising: using a first fuel balancing circuit to selectively supply fuel directly to said engines from said first and second fuel reservoirs, and to selectively transfer fuel between said first and second fuel reservoirs to balance said first and second fuel reservoirs in weight; and using a second fuel balancing circuit to supply fuel from said third fuel reservoir to said pair of engines, and to selectively transfer fuel from said third fuel reservoir to either of first and second fuel reservoirs to balance fuel levels in said first and second fuel reservoirs; and using an operator control panel to selectively control which of said first and second fuel balancing circuits are used. 16. The method of claim 15, wherein using a first fuel balancing circuit comprises selectively transferring fuel between said first and second fuel reservoirs without interrupting a supply of fuel flow to either of said engines. 17. The method of claim 15, wherein using a first fuel balancing circuit comprises using said operator control panel to control a flow control valve and a plurality of pumps operably associated with said first and second fuel reservoirs to selectively transfer fuel between said fuel reservoirs while both of said engines are operating. 18. The method of claim 15, wherein using a first fuel balancing circuit comprises selectively transferring fuel between said first and second fuel reservoirs while said engines are not operating. 19. The method of claim 15, wherein using said a fuel balancing circuit comprises controlling a plurality of pumps associated with said third fuel reservoir, and valves associated with each of said first and second fuel reservoirs, to selectively transfer fuel from said third fuel reservoir to either of said first and second fuel reservoirs to balance fuel levels in said first and second fuel reservoirs. 20.
