+ * The <<<JumpableUniformRandomProvider>>> interface allows creation of a copy of the generator and
+ advances the state of the current generator a large number of steps in a single jump. This can
+ be used to create a set of generators that will not overlap in their output sequence for the
+ length of the jump for use in parallel computations.

+ In the above example, the source is known to implement the <<<JumpableUniformRandomProvider>>> interface.
+ Not all generators support this functionality.
