Detailed Description

Initializes a Camera Model.

This factory class is used to obtain a Camera Model object given a PVL which contains a valid Instrument group. The Instrument group can come from an image/cube or a hand-created PVL file. The camera is loaded based on information using the SpacecraftName and IntrumentID contained in the Instrument group. It is plugin oriented. That is, this class looks in $ISISROOT/lib/Camera.plugin to convert the SpacecraftName and IntrumentID string into a pointer to the appropriate camera class (e.g., Viking, HiRISE, etc.). This allows programmers who develop new camera models to create a plugin without the need for recompiling all the Isis applications that use camera models.
