 I propose we switch back before release. I'm flagging this for 2 reasons

 1) It's a breaking change from 2.0
 2) We dinged pramsey for trying to sneak in use of degrees in his
 ST_Project function.

 Our general convention is to use radians unless if there is another over-
 aching standard that requires degrees and just demonstrate in the docs how
 to flip between the two using the built in PostgreSQL degrees and radians
 functions as demonstrated in:
