Signals a range of long values, the first after some initial delay and the rest periodically after.
<p>
The sequence completes immediately after the last value (start + count - 1) has been reached.

@param start that start value of the range
@param count the number of values to emit in total, if zero, the operator emits an onComplete after the initial delay.
@param initialDelay the initial delay before signaling the first value (the start)
@param period the period between subsequent values
@param unit the unit of measure of the initialDelay and period amounts
