What steps will reproduce the problem?
1. 'compile' command in the mex directory on OSX in Matlab

What is the expected output? What do you see instead?
Expect to see it compile but instead I get a bunch of linking errors
related to the Newmat library.

What steps will reproduce the problem?
1. Any XML scene definition that uses meshes


What is the expected output? What do you see instead?

Inclusion of mesh files in the XML definition require the user to specify
the *.obj or *.stl files. If absolute paths are used then on windows
machines the drive letter will be included. However on Linux and OSX just
the root '/' is needed. Relative paths could be used but these are tricker
to understand and implement. 

The current work-around is that cross-platform users must have separate XML
scene definition files for all OSes.

Possible solution?

1. Create a new global scene parameter to specify the model directory. That
way changes for each OS are very localized in the file.
2. Pass in model directory as a runtime argument to the library.

Need to wire the old variable structure to update a node's position/orientation 
in the scene graph.

Just need to wrap up the node class.

Perform testing of the coordinate transform class.

What steps will reproduce the problem?
1. calling sceneGetAABB() in matlab 

What is the expected output? What do you see instead?

I expect to see a reasonable output, but instead I see the numerical
equivalent for +/- infinity for the values. Example:

{{{
>> aabb = sceneGetAABB()

aabb =

  1.0e+038 *

   -3.4028    3.4028   -3.4028    3.4028   -3.4028    0.0000
}}}

Incorporate Boost serialize library to save/load Scene.

Problem: How to best link XML transform tags, XML body tags (and geoms) with 
the internal scene 
graph model and variables.

Possible solutions:
1. For every transform, internally create a Node and place it in the graph. 
Intermediate transforms 
will have a generic name assigned. Once intermetiate transforms are created, 
Bodies (and geoms) 
are simply attached to the last intermediate node. Any node that needs to 
listen to a variable will be 
linked against that variable during building of the tree.
2. Transform tags modeled internally as a series of executions (this is how its 
done now).

 Need to integrate Lin-Canny distance query algorithm into SceneML.
