11628	[Patch] Added documentation to EastNorth, changed x - y = y.sub(x) to x.subtract(y) and minor code style improvements.	michael2402	team	"An access to x is not much faster than a east()-method call, since the JIT can inline that access.

The current meaning of sub is to subtract from. I changed it to a normal subtract, which has the same meaning as in Point2D."	enhancement	closed	normal	15.08	Core		fixed	gsoc
