//year should be a valid full year (ie: 1978)
//month should an integer from 1 to 12
//day should be a valid day of the month
//unit specifies the unit to display the age in. Valid values are "years", "months", or "days"
//decimals specifies the number of trailing decimals. Valid values are 0 and above
//rounding specifies whether to round up or down the age. Valid values are "roundup" or "rounddown"
//displayage (year, month, day, unit, decimals, rounding)
//eg, displayage(1997, 11, 24, "years", 0, "rounddown")
