GeocentricCRS (GeoAPI normative 3.1-SNAPSHOT)

All Superinterfaces:

CoordinateReferenceSystem, GeodeticCRS, IdentifiedObject, ReferenceSystem, SingleCRS
```
@UML(identifier="SC_GeocentricCRS",
     specification=ISO_19111,
     version=2003)
public interface GeocentricCRS
extends GeodeticCRS
```
A 3-dimensional coordinate reference system with the origin at the approximate centre of mass of the earth. A geocentric CRS deals with the earth's curvature by taking a 3-dimensional spatial view, which obviates the need to model the earth's curvature.
This type of CRS can be used with coordinate systems of type Cartesian or Spherical.

Departure from OGC/ISO specification:
This interface is kept conformant with the specification published in 2003. The 2007 revision of ISO 19111 removed the SC_GeographicCRS and SC_GeocentricCRS types, handling both using the SC_GeodeticCRS parent type. GeoAPI keeps them since the distinction between those two types is in wide use.
