+This repository includes basic implementations of 1D, 2D, and 3D bodies, as well as a GIS body type that uses the 
+Haversine formula for precise distances along the earth's surface at the cost of increased computational demands.
+For each of these, there is also a convenience class called Simple[X]GravityModelDistribution to reduce the number

 SimpleGravityModelDistribution is a simple O(N) computation over all bodies, parallelized with Streams for quick execution. 
 This implementation could be easily extended by implementing a new Body type for your use case, such as computing the gravity
