Templates for POV-Ray poly{} objects, meant for 
cutnpasting into scene files. These are all prefilled 
with 0's  and labels to make it easier find and fill 
in the appropriate polynomial coefficients. 

The numbers in the labels are all exponents. 
i.e. /*y2z3*/ represents y^2 z^3

For example
       x^2 + xz- 5x + y^2 - 1 = 0
becomes:
     poly{2,
     <
     1 /*x2*/,   0 /*xy*/,   1 /*xz*/,   -5 /*x*/,   1 /*y2*/,
     0 /*yz*/,   0 /*y*/,    0 /*z2*/,    0 /*z*/,  -1 /*constant*/

  This is a very useful contribution. Thank you for contributing it
to the people here.

I just put a fixed version in binaries.tutorials.
(There was an error in the poly{7} labels).
These are now ready to be put into the Insert Menu
folder.

They actually landed in binaries.utilities
