DORIS: Math libs

[Brian Hook]

I know Doris has some primitive math stuff, but it's not all that, um, 
fleshed out.  I posted to lua-l about this, and they don't seem to 
know of any standard 3d math lib.  How do you feel about making one a 
part of doris, or possibly even standalone?

I'm just thinking a generic generalized Vector and Matrix library with 
no real thought to performance, just something for quick and dirty 
(but robust) hacking.
