Bring Mersenne Twister code into morphologica

[sebjameswml]

This is the rng.h in AttractorScaffolding, BUT, it needs to be modified so that it can generate 64 bit random numbers; at present it is a 32 bit implementation.

Consider also incorporating siderand to obtain entropy from the CPU.

See "Stronger Cryptography For Every Device, Everywhere" by J V Roig.

Maybe use "SIMD-Oriented Fast Mersenne Twister: a 128-bit Pseudorandom Number Generator" by Mutsuo Saito & Makoto Matsumoto

[sebjameswml]

...which is https://doi.org/10.1007/978-3-540-74496-2_36

[sebjameswml]

...code here: http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/index.html#SFMT

Update: C++-11 has nice random number generators, so this should be "Wrap C++-11 random number generation in some convenience functions"

The stuff about siderand may still hold - compare that with the standard C++ mechanism for collecting entropy.

Fixed, with addition of Random.h.
