PandaNode

Although the bam file format is general enough to store a list of objects of arbitrary type, bam files on disk usually contain just one object, a PandaNode that is the root of a scene graph.

(Bam files that store other kinds of things are usually given the extension "boo", for "binary other objects", to differentiate them from the normal scene graph type file.)

This is a convenience method for when you believe you are reading a scene graph bam file. It reads the one PandaNode and returns it. It also calls resolve() to fully resolve the object, since we expect this will be the only object in the file.

If the bam file contains something other than a PandaNode, an error is printed and NULL is returned.
