usage

the function returns a string array with the days as requested,
**************************************************************************
Arguments:
>dateObj = a date object which will be taken as a reference or null for today
>dayNum = number of days to return, can be positive or negative
>dayFormat = 1 for full day name, 0 - short name, null - no day name
>monthFormat = 1 for full month name, 0 - short name, null - no month name
**************************************************************************
Example usage
[code]
myDaysArry = returnDays(null, -5, 1, 0)
//null for today as reference
//-5 for five days back from today, i.e. yesterday, the day before yesterday etc...
//1 for full day name display
//0 for short month name
[/code]
return something like
Thursday, May 6
Wednesday, May 5
