A seeded Random Data Generator.
Access via Phaser.Math.RND which is an instance of this class pre-defined
by Phaser. Or, create your own instance to use as you require.
The Math.RND generator is seeded by the Game Config property value seed.
If no such config property exists, a random number is used.
If you create your own instance of this class you should provide a seed for it. If no seed is given it will use a 'random' one based on Date.now.

Call this method with no parameters to return the current state.
If providing a state it should match the same format that this method
returns, which is a string with a header !rnd followed by the c,
s0, s1 and s2 values respectively, each comma-delimited.
