 `init_state` is the starting state for the RNG, you can pass any 64-bit value.  
 `init_seq` selects the output sequence for the RNG, you can pass any 64-bit value, although only the low 63 bits are significant.

+#### rng.tinymt32()
+
+Creates a TinyMT32 generator instance with a entropy-based seed of 4 elements. You should use this if you don't care about explicitly providing a seed.

+#### rng.tinymt32(`seed`)
 
+Creates a TinyMT32 generator wth a given seed. You can pass any 64-bit value, but 0 will have the same result as a random seed.
+You should use this to specify the seed.
