Updated the README.
Configure Maven.
Create all skeleton classes. Note that the mathematics/Mathematics class is originally mathematics_functions.h since mathematics.h contains only includes. The file decimal.h has been excluded since it contains only includes. configuration.h was put into its own package and broken into three separate classes.
Updated README with specifics about the physics engine.
Added developers section and dependencies to pom.xml.
Added original LICENSE and VERSION.
Fixed formatting.
Finished converting "configuration.h".
Finished converting Body.cpp/Body.h, CollisionBody.cpp/CollisionBody.h and RigidBody.cpp/RigidBody.h. There were several structs which were added as explicit classes. These should be eventually converted to static nested classes.
