Concept 1.9 : Order of Transformations III
==========================================

Idea:
=====
Here we provide a template where you can store
the effects of different rotation, and translation
parameters and specify the order in which they
are to be performed.

Experiment:
===========
Try the following parameters :
Translate by (2, 3, -5)
Rotate by 45 degrees along X=1, Y=1, Z=0
Click on Store and execute.

Now click the option "Rotate then Translate"
Now Store and execute again.  The effects of the
order in which the transformation is specified
affects the final position of the cube.

Try giving some of your own values and get 
comfortable with the concepts of translation,
rotation, and order in which they are specified.

The following keyboard commands help change the

(x, X), (y, Y), (z, Z) help navigate away from
or towards the orign along the respective axis.
