/**
* Wrapper around http://www.frequency-decoder.com/2009/09/09/unobtrusive-date-picker-widget-v5/
*
* Because many options take a date with the format of YYYYMMDD there is a utility method:
* ERMDatePicker.optionsStringForTimestamp(NSTimestamp ts) that will return a correctly formatted
* string for a given NSTimestamp.
*
* @binding dateIn an NSTimestamp supplying the value for the field (required)
* @binding cssFile name of the css file (defaults to datepicker.css)
* @binding cssFramework name of the framework containing the css file (defaults to ERModernDirectToWeb)
* @binding dateformat string containing the date format for the field
* @binding injectStylesheet choose whether to dynamically inject the datepicker.css at component load.
* if used in a ajax loaded component, it may be safer to load this manually.
*
* See date-picker documentation for following optional values:
*
* @binding hightlightDays string - identifies days to highlight on the calendar (format: [0,0,0,0,0,1,1])
* @binding rangeLow string - date in format YYYYMMDD defining the lowest selectable date
* @binding rangeHigh string - date in format YYYYMMDD defining the highest selectable date
* @binding disabledDays string - identifies days on calendar that are disabled (format: [1,0,1,0,1,0,1])
* @binding disabledDates string - date range of disabled dates (format: YYYYMMDD:YYYYMMDD or YYYYMMDD if single date)
* @binding enabledDates string - date range of enabled dates (format: YYYYMMDD:YYYYMMDD or YYYYMMDD if single date)
* @binding noFadeEffect boolean - disables fade in/out effect
* @binding finalOpacity number - sets final opacity (20 - 100)
* @binding showWeeks boolean - show week numbers
* @binding noTodayButton boolean - hide the "Today" button
* @binding cursorDate string - date in format YYYYMMDD that sets the default cursor date
* @binding dragDisabled boolean - disable dragging of calendar
* @binding fillGrid boolean - fill all dates, not just those in current month
* @binding constrainSelection boolean - if fillGrid is yes, constrain selection to current month (defaults to true)
* @binding hideInput boolean - hide the input field (don't use if hideControl is specified)
* @binding hideControl boolean - hide the calendar button (don't use if hideInput is specified)
