OSL: Small C++ Utility Routines

Here's a bunch of small, self-contained utility routines
to evaluate various mathematical functions, make portable
OS functions. Just read the header files to see how
they work--everything should be copiously commented.
You should be able to pick out one or two header files,
and use them without using anything else here. You may
have to follow the #includes to find the few other OSL
headers these routines rely on. Linking should also be
easy--if you use the .h file, build the .cpp file too.
To get the files:
git clone git://github.com/olawlor/osl.git
All these files have built recently on:
- Windows machines with Visual C++
- Mac OS X machines with xcode
- Linux machines with gcc 4
But of course some minor tweaking may be needed.
No major "porting" changes should be necessary.
Of particular scientific computing and mathematical interest:
vector1d-4d.h: spatial vector class, with +, -, dot, cross, etc.
random.h/.cpp: pseudorandom number generators for int, float, etc.
"Random48" or better is recommended for Monte Carlo.
random_vector.h: 2D and 3D random vectors over cubes and spheres.
statistics.h: means, variances, standard deviations in an easy interface.
Of particular computer graphics interest:
vec4.h: GLSL-style "vec3" and "vec4" classes, with overloads.
vector3d.h: spatial vector class, with +, -, dot, cross, etc.
vector_util.cpp: non-inlined routines for vector1d-4d.
viewpoint.h/.cpp: 3D projective camera class.
perlin_noise.h/.cpp: smooth 3D noise function (by Ken Perlin).
Of particular networking interest:
socket.h/.cpp: portable easy-to-use TCP socket wrapper.
sha1.h/.cpp: Secure Hash Algorithm-1. FIPS standard crypto hash.
sha2.h/.cpp: SHA-256 hash.
authpipe.h/.cpp: network protocol for secret-key
authentiated messaging.
webserver.h/.cpp: simple HTTP server
webservice.h/.cpp: simple HTTP client
webconfig.h/.cpp: modify application variables via HTTP
Portability functions:
dir.h/.cpp: portable directory traversal (list files in a directory)
dll.h/.cpp: portable dynamically linked library interface.
porthread.h/.cpp: portable threading library
