/**
* @author Kevin Roast
*
* Custom FreeMarker Template language method.
* <p>
* Compare two dates to see if they differ by the specified number of miliseconds
* Perform a test to see how two dates compare, optionally offset by a specified number of milliseconds.
* <p>
* Usage:
* dateCompare(dateA, dateB) - 1 if dateA if greater than dateB
* dateCompare(dateA, dateB, millis) - 1 if dateA is greater than dateB by at least millis, else 0
* dateCompare(dateA, dateB, millis) - 1 if dateA is greater than dateB by at least millis, else 0
* dateCompare(dateA, dateB, millis, test) - same as above, but the 'test' variable is one of the
* following strings ">", "<", "==" - greater than, less than or equal - as the test to perform.
