Arduino library for random number generation with Python random interface.

This library uses the Marsaglia PRNG to generate random numbers. The numbers generated by the PRNG are good for most "hobby" applications e.g. games or simulations.

It has different ways to seed the PRNG, which allows reseeding at any time. This allows e.g. an exact rerun of a simulation.

#include "Prandom.h"

• Prandom() create Prandom object with seed based upon micros() and millis().
• Prandom(uint32_t s) create Prandom object with defined seed.

• void seed() seed based upon micros() and millis().
• void seed(uint32_t s, uint32_t t = 2) seeds for Marsaglia PRNG; need 2 seeds, but 1 will work too.

• uint32_t getrandbits(uint8_t n) idem
• uint32_t randrange(uint32_t stop) randrange() does not include stop value (0..stop-1).
• uint32_t randrange(uint32_t start, uint32_t stop, uint32_t step = 1)
• uint32_t randint(uint32_t start, uint32_t stop) randint() does include stop value (start..stop).

• float vonmisesvariate(float mu, float kappa = 0) mu is mean angle in radians, kappa is concentration parameter, 0 -> uniform.

• improve documentation.

• unit tests?
• follow developments in Python random library.
• add examples.

• add more RNG's to choose from.
• CamelCase functions.
