 * @group jak-widgets
 * @static
 * @example
 * Pro inicializaci 1,2,3 polickove konstelace lze pouzit:
 * JAK.Calendar.Setup.setup(false, "[vybrat datum]", {pickTime: true, defaultFormat:["j.n.Y", "H:i"]}, ["calendar_value","calendar_time_value"]);
 * JAK.Calendar.Setup.setup(false, "[vybrat datum]", {pickTime: true, defaultFormat:["j.n.Y", "H","i"]}, ["cdate","chour","cmin"]);
 * JAK.Calendar.Setup.setup(false, "[vybrat datum]", {pickTime: false, defaultFormat:["j.n.Y"]}, ["fulldate"]);
