* Only the first parameter is mandatory. Either the second, the third, or both
* may be left out.
*
* If only one parameter is present, the function yeilds a true value on the
* weekday that the parameter represents. If the string "GMT" is specified as
* a second parameter, times are taken to be in GMT, otherwise in local timezone.
*
* If both wd1 and wd1 are defined, the condition is true if the current weekday
* is in between those two weekdays. Bounds are inclusive. If the "GMT" parameter
* is specified, times are taken to be in GMT, otherwise the local timezone is
* used.
*
* Valid "weekday strings" are:
*
* SUN MON TUE WED THU FRI SAT
*
* Examples:
*
* ``` js
* weekdayRange("MON", "FRI")
* true Monday trhough Friday (local timezone).
*
* weekdayRange("MON", "FRI", "GMT")
* same as above, but GMT timezone.
*
* weekdayRange("SAT")
* true on Saturdays local time.
*
* weekdayRange("SAT", "GMT")
* true on Saturdays GMT time.
*
* weekdayRange("FRI", "MON")
* true Friday through Monday (note, order does matter!).
* ```
*
*
* @param {String} wd1 one of the weekday strings.
* @param {String} wd2 one of the weekday strings.
* @param {String} gmt is either the string: GMT or is left out.
* @return {Boolean}
