* Calculate the allowance array or traffic used array

* If:

* + UPLOADS are charged and there are no PEAK/OFFPEAK periods (therefore all
* traffic is charged), the allowance will be shown as 1 metric - TRAFFIC.
* + UPLOADS are charged and there are PEAK/OFFPEAK periods the allowance
* will be shown as 2 metrics - PEAK/OFFPEAK.
* + UPLOADS are NOT charged and there are no PEAK/OFFPEAK periods the allowance
* will be shown as 1 metrics - TRAFFIC.
* + UPLOADS are NOT charged and there are PEAK/OFFPEAK periods the allowance
* will be shown as 2 metrics - PEAK/OFFPEAK.
*
* Thus:
*
* + If base_x_Y is NULL, all Y traffic is FREE (ignore respective extra_x_Y setting).
* + If base_x_Y is a number, all Y traffic is FREE up to the number (evaluate extra_x_Y setting).
* + If extra_x_Y is a number, charge this amount for traffic over base_x_Y.
* + If extra_down_peak is NULL this is invalid, treat base_down_peak as NULL
* + If extra_down_offpeak is NULL add traffic_down_offpeak to traffic_down_peak
* + If extra_up_peak is NULL add traffic_up_peak to traffic_down_peak
* + If extra_up_offpeak is NULL add traffic_up_offpeak to traffic_down_offpeak
*
* @param array Traffic Used in each metric.
* @param bool Whether the output should be a string
* @param bool Display the over allowance numbers
