- added Mesh.MVert(); can now create 'thick' vertices which don't wrap mesh

- implemented slice operations (get/set) for vertex list; allows script
  writers to manipulate lists of vertices (using 'thick' vertices)
- fixed problem in mesh.faces.extend() which allowed the creation of
  "Eeekadoodle" faces
- added mesh.update() method; (possibly) temporary fix to allow updating DAG

   The MVertSeq object
   ===================
     This object provides sequence and iterator access to the mesh's vertices.
+    Access and assignment of single items and slices are also supported.
+    When a single item in the vertex list is accessed, the operator[] returns
+    a MVert object which "wraps" the actual vertex in the mesh; changing any
+    of the vertex's attributes will immediately change the data in the mesh.
+    When a slice of the vertex list is accessed, however, the operator[]
+    returns a list of MVert objects which are copies of the mesh's vertex
+    data.  Changes to these objects have no effect on the mesh; they must be
+    assigned back to the mesh's vertex list.
+
+    Slice assignments cannot change the vertex list size.  The size of the
+    list being assigned must be the same as the specified slice; otherwise an
+    exception is thrown.
+
+    Example::
+      import Blender
+      from Blender import Mesh
+
+      me = Mesh.Get("Plane")          # get the mesh data called "Plane"
+      vert = me.verts[0]              # vert accesses actual mesh data
+      vert.co[0] += 2                 # change the vertex's X location
+      pvert = me.verts[-2:]           # pvert is COPY of mesh's last two verts
+      pvert[0].co[0] += 2             # change the vertex's X location
+      pvert[1].co[0] += 2             # change the vertex's X location
+      me.verts[-1] = pvert[1]         # put change to second vertex into mesh
