move this into MapData class

the purpose of this class is to have a common location with methods used to define random points in solar systems based on planet and moon positions. GetRandPointOnPlanet() will query solar systems for planets, pick a random planet, and define a coordnate within that planet's bubble. GetRandPointOnMoon() does same as above, but using moons. Get2RandPlanets() will pick a random point between 2 planets, for warp-out/warp-in and other things as we see fit. Get3RandPlanets() does same as above, but using 3 planets. GetRandPointInSystem() will define a random point within a given system.

this class of methods should be used for positioning mission space, cosmic signatures, anomolies, complexes, and other things needing a random position in a given system.

these methods will also be used for random npc spawns and their warping/movement.

class DBGPointEntity has index, itemID, radius, and position, and is found in SystemDB. see copy of class declaration below

NOTE i seem to remember that ALL COSMIC SPAWNS are within 6au from planets. ....cant find that info now. -allan 31Jul14int64 MakeRandomInt( int64 low, int64 high ) double MakeRandomFloat( double low, double high )
