Namespaces
namespace	theoretica
	Main namespace of the library which contains all functions and objects.

Typedefs
using	theoretica::pseudorandom_function = uint64_t(*)(uint64_t, std::vector< uint64_t > &)
	A function pointer which wraps a pseudorandom generator, taking as input the previous generated value (or seed) and the current state of the algorithm.
