b2f520df12990a4f0c393c2fb9b6f9b1449aef70Dav Glass * The Calendar component is a UI widget that allows users
c0d83403b13f02bc6fdcf62a712de150a7f974e2Dav Glass * to view dates in a two-dimensional month grid, as well as
c0d83403b13f02bc6fdcf62a712de150a7f974e2Dav Glass * to select one or more dates, or ranges of dates. Calendar
c0d83403b13f02bc6fdcf62a712de150a7f974e2Dav Glass * is generated dynamically and relies on the developer to
c0d83403b13f02bc6fdcf62a712de150a7f974e2Dav Glass * provide for a progressive enhancement alternative.
