This is for quickly generating a random true, or false. It is useful for being able to randomly chose to do something, such as choosing if the enemy should fire at the player.

### randBoolean()

Randomly returns true or false. On average, it aims to have a 50% chance to return true or false.

### randBoolean( probability )

Randomly returns true, but the likely hood is based on the 'probability' value. The chance of returning true is '1 in probability', where tries is a positive integer.

`// a 1 in 10 chance of executing the if statement`

if randBoolean(10)

// do something

end

So if 'probability' is 10, then it is a 1 in 10 chance, and if 'probability' is 100, then it has a 1 in 100 chance of returning true.
