Implement a correct sample shape object

[Steve Williams]

Martyn Gigg asked Steve to

"... properly define a sample shape object that knows how to calculate its volume. This can then be saved as an XML string and recreated when reloaded. This will require:

Modifying ISIS LoadRaw/LoadNexus to create a sample shape object using the CreateSampleShape algorithm; Add the ability of objects to calculate their own volume based upon a triangulated wire mesh that is used to approximate them. At the moment the primitive shapes such as cylinders are defined by a low resolution mesh and we want to be able to be able to specify as a parameter whether we want a low/high resolution triangulation."
