Random selection and number generation

A constructor to create a new Random object. If a seed is given, the random number generator will use it as an initial seed value. This makes the number sequence it generates reproducable for testing purposes.

seed optional seed value

Random.prototype.number()

Returns a random number between 0 (inclusive) and 1 (exclusive). Effectively the same as Math.random(), but uses the random number generator of this Random object.

Random.prototype.pick( m, n )

Returns a random integer between m (inclusive) and n (inclusive).

`m`	one end of the range
`n`	the other end of the range

Random.prototype.pickOtherThan( m, n, excluded )

Returns a random integer between m (inclusive) and n (inclusive), but excluding the value of excluded.

`m`	one end of the range
`n`	the other end of the range
`excluded`	a value that will never be returned

Random.prototype.d6()

Returns the result of rolling a simulated 6-sided die. A convenience for Random.pick( 1, 6 ).

Random.prototype.rollDice( [n], [showDice] )

Simulates rolling n dice. If showDice is true, an image of each die result is printed to the console. The values rolled are returned in an array.

`n`	the optional number of dice to roll (default is 1, must be non-negative)
`showDice`	if `true`, the results are printed to the console graphically (default is `true`)

returns an array containing the n numbers that were rolled
