+This is a pretty standard mesh for the same as used in the skinning example.  It's a 6 
+sided cylinder divided into 6 sections with a total of 42 vertices.  It is used as the

+*******************************************************************************************
+This mesh is the same as the one above, but one of the rings of verticies has been moved 
+outwards to create a bulge in the middle of the cylinder.  This geometry is used as the
+morph target (aka deformer or blend shape) in the morph controller.
+
+A morph can operate on ANY or ALL of the sources so you could morph positions, UVs and 
+normals all at the same time.  The sources to be morphed have to be referenced by <input>
+tags inside the <vertices> tag in both the morph target and the base mesh.  In this example
+only the positions are referenced by the <vertices> tag so they are all this morph will effect.
+
+Since only the positions are being morphed, everything but the target__pCylinderShape1-positions
+source and the <vertices> tag could be deleted from this <geometry> and it the morph
+should still work.  The DCC tool should get all the other information from the base mesh, so
+there is no need to duplicate it here.
+
+This extra information may still be exported by some DCC tools for a variety of reasons.
+The only time it is actually REQUIRED is if the morph target geometry is also instantiated in
+the scene by having an <instance_geometry> tag point directly to it's geometry tag.
+
+Due to a bug in the ColladaMaya Maya expects the polylist information to be present in the 
+morph target or the morph will not be instantiated.

+This source defines a weight for each vertex and each joint.  The weight defines how much
+a particular joint will contribute to moving a particular vertex's position.  This allows
+several joints to influence vertices by different amounts, giving a nice smooth bend.
+
+Since there are 42 vertices and 7 joints there should be at most 294 weights.  In this case
+the skinning algorithm was told that each vertex should be effected by the 5 nearest joints
+so we have 5 weights per vertex giving a total of 210.  Maya has thrown in an extra weight
+of 1 at the beginning giving us a total of 211.
+
+Weights 1-6 will be applied to the first vertex, you can see how they work.  The first weight
+represents the closest joint to the vertex and has the largest value, the remaining 4 weights
+get smaller and smaller as the associated joint gets farther from the vertex.

+The vertex_weights tag associates the weights and joints from the previously defined

+Each weight/joint pair is referred to as an "influence", a vertex can have any number of

+This is the node hierarchy that represents the skeleton of the skinned object.
+The first node has an ID to act as a starting point for SID searches, the rest
+of the nodes in the hierarchy only need SIDs.  It is preferable to use SIDs to
+identify the joints of the skeleton because it allows the skin controller to be
+used several times with different skeletons.  For example we could have a second
+joint hierarchy using the same SIDs but with a different id (like skeleton2_root)
+on the first node and different transforms.  
+
+In this example the root joint of the skeleton is 20 units above the ground.  
+All the other joints are 30 units apart in the Y direction.  A Z rotation has been
+added to some of the joints to cause the skinned/morphed cylinder to gradually bend so
+you can see the skinning effect.

+Some people try to put the instance_controller here.  This will not work correctly for
+a skin because the skinning process has already transformed all the vertices using the
+full transform in the joints that the skin controller references. This means the data
+coming out of the instance_controller is effectively in world space.  If we put the 
+instance_controller here, the geometry coming out of it would be transformed (again) by 
+this node, moving it up an additional 20 units.
