Command prior manage pixel priors defined for a PhyGeo project.

The argument of the command is the name of the project file.

By default, the command will print the currently defined pixel priors into the
standard output. If the flag --add is defined, the indicated file will be used
as the pixel prior of the project.

If the flag --set is defined, it will set a pixel prior to a raster value. Th
 sintaxis of the definition is:

	<value>=<probability>

If there is no pixel prior file defined in the project, a new file will be
created using the project file name as a prefix and "-pix-prior.tab" as a
suffix.
