/*
 * Test sketch based on rand-period-test.c by @unprovable 

 * His sketch shown an anomaly with Arduino's PRNG, in which the LCG period seems to be unreliable.
 * Also the function seems to be quite slow; iterating over the stream until we get back to the beginning
 * takes 199340888ms (55.3724689 hours). It takes 1.5 minutes (approx) to generate 1M numbers.

 * So I decided to repeat the test with a textbook implementation of a standard LCG to see if we can get a
 * reliable generator with a stable period (and hopefully faster runtime) under the same conditions.
