public Range withStep(Integer step) {

<p>
The step value for the range. For example, if you have a range of 5,000 to 10,000, with a step value of 1,000,
the valid values start at 5,000 and step up by 1,000. Even though 7,500 is within the range, it isn't a valid
value for the range. The valid values are 5,000, 6,000, 7,000, 8,000...

@param step
