/**
This is the main function you'll call from the onClick event of a button.
Normally, you'll have something like this on your HTML page:

Start Date: <input name="StartDate">
<input type=button value="select" onclick="displayDatePicker('StartDate');">

That will cause the datepicker to be displayed beneath the StartDate field and
any date that is chosen will update the value of that field. If you'd rather have the
datepicker display beneath the button that was clicked, you can code the button
like this:

<input type=button value="select" onclick="displayDatePicker('StartDate', this);">

So, pretty much, the first argument (dateFieldName) is a string representing the
name of the field that will be modified if the user picks a date, and the second
argument (displayBelowThisObject) is optional and represents an actual node
on the HTML document that the datepicker should be displayed below.

In version 1.1 of this code, the dtFormat and dtSep variables were added, allowing
you to use a specific date format or date separator for a given call to this function.
Normally, you'll just want to set these defaults globally with the defaultDateSeparator
and defaultDateFormat variables, but it doesn't hurt anything to add them as optional
parameters here. An example of use is:

<input type=button value="select" onclick="displayDatePicker('StartDate', false, 'dmy', '.');">

This would display the datepicker beneath the StartDate field (because the
displayBelowThisObject parameter was false), and update the StartDate field with
the chosen value of the datepicker using a date format of dd.mm.yyyy
