Gets default envelope of coordinate system.

Coordinate systems which are bounded should return the minimum bounding box of their domain. Unbounded coordinate systems should return a box which is as large as is likely to be used. For example, a (lon,lat) geographic coordinate system in degrees should return a box from (-180,-90) to (180,90), and a geocentric coordinate system could return a box from (-r,-r,-r) to (+r,+r,+r) where r is the approximate radius of the Earth.
