Services for object manipulation 

Hi,

I've added some services for receiving information of, and manipulating objects in a scene: 

- getting the bounding box of an object
- setting the pose of an object
- transforming a 3D point into the coordinate frame of an object

The idea is to teleport objects around without re-starting the simulation. The bounding box information will be used to place objects randomly on objects with planar surfaces (eg tables). The generation of randomized positions of objects is currently under development, but if it would be useful for other MORSE users it can be made publicly available at a later point in time.

As I am very new to MORSE please let me know what you think of the services, whether they are necessary, and how they could be improved.

thanks,
Lars
