Added the ability to generate a tensor from a custom user defined 'generator'. This simplifies the creation of constant tensors initialized using specific regular patterns.
...
Created a gaussian window generator as a first use case.

Improved the tensor random number generators:
...
* Use a mersenne twister whenebver possible instead of the default entropy source since the default one isn't very good at all.
* Added the ability to seed the generators with a time based seed to make them non-deterministic.
