@method every(<increment>, [fn])
@returns Array
@short Iterates through the DateRange for every <increment>, calling [fn] if it is passed. Returns an array of each increment visited.
@extra When <increment> is a number, increments will be to the exact millisecond. <increment> can also be a string in the format %{number} {unit}s%, in which case it will increment in the unit specified. Note that a discrepancy exists in the case of months, as %(2).months()% is an approximation. Stepping through the actual months by passing %"2 months"% is usually preferable in this case.
@example

Date.range('2003-01', '2003-03').every("2 months") -> [...]
