New code and tutorial

A new directory has been added to vmtk, called vmtkApps. It will contain application-specific code built on top of vmtk.

As a first entry, Marina Piccinelli (Emory Univ) has contributed an implementation of Matthew Ford’s algorithm for digital removal of cerebral aneurysms (Ford et al, BJR 2009). Check it out with the tutorial. The code is at the vmtk repository.
