GravitationalForceGenerator(source:ISimulatable, gravitationalConstant:Number = 1.2)
Creates the Force Generator
GravitationalForceGenerator
  
generate(element:ISimulatable):void
Generates the gravitational force on the supplied element

We find the source through the following equation: 

   F = G m1 m2 / r^2
where: 
   F is the force we're solving for (applied along the bodies' difference vector)
   G is a gravitational constant
   m1/m2 are the masses involved in the exchange (here, the force is only applied to element)
   r is the distance between the bodies

public function GravitationalForceGenerator(source:ISimulatable, gravitationalConstant:Number = 1.2)

Creates the Force Generator

Parameters
source:ISimulatable — source of gravitational pull
 
gravitationalConstant:Number (default = 1.2) — magic constant (trial and error per simulation)

Throws
— if source has infinite mass
