Support for colored binary STL

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Export a binary STL with "keep color" option (i did it with Autodesk 
Inventor 2014)
2. load your STL with JSC3D

What is the expected output? What do you see instead?
i expected JSC3D to have an option to render objects using theyr original RGB 
color

What version of the product are you using? On what operating system?
1.6.5

Please provide any additional information below.
if you open a binary STL file u will notice that the STL RGB color code is 
stored in bytes 1E-20.
These bytes are preceded by "COLOR="
