/**
* This {@link NachoDateRangeMatcherEditor} uses
* NachoCalendar DateField

*
*
* Extension: NachoCalendar This Glazed Lists extension requires the third party library NachoCalendar. Tested Version: 0.23 Home page: http://nachocalendar.sourceforge.net/ License: LGPL
*
* It provides a single hook for customizing the layout and/or look of the
* DateFields in the form of a local factory method which produces the entire
* component, {@link #createComponent}. Subclasses may override that method to
* decorate and customize the look of this {@link NachoDateRangeMatcherEditor} as
* needed.
