New Character property system?

Hello all. I was looking thru the new 1.7.0 API and stumbled across GravityWalker class(http://www.panda3d.org/reference/python/classcontrols_1_1GravityWalker_1_1GravityWalker.php#a53885edfc3d07e1c057ec06ced46d7bc). I know documentation for the new SDK is not complete, but does this new class contain an easier way to implement character motion? If so, how would I use it?

Thanks,
