/***
 * Smart(hostname)
 *
 *  DESCRIPTION
 *    Creates an instance of a SMART object.
 *    This constructor takes a mandatory SMART hostname.
 *
 *  SYNOPSIS:  
 *    Smart([SMART hostname])
 *
 *  EXAMPLE:
 *    var _smart = new Smart("111.111.111.111");
 *
 *    NOTE: there is a global SMART_HOST javascript constant created in begin_nav
 *    which you can use to pass to your SMART object:
 *    
 *      eg. var _smart = new Smart(SMART_HOST);
 *
 * INSTANCE METHODS
 *  getInStoreItem(inStoreItemArr)
 *    returns Item data in XML
 *
 *  getInStoreItemsPriceAndName(upc)
 *    returns Item and Name data in XML
 *
 *  getAssociateData(associate)
 *    returns Associate data in XML (grandfather method)
 *
 *  getAssociateDataByBadgeId( badgeid )
 *    returns new associate logon data in XML
 *
 *  getAssociateDataByUserInfo( userid, password, hiredate )
 *    returns new associate logon data in XML
 *    userid and password should be escaped before being passed
 *    as parameters to this method
 *
 *  getTaxFlags(upc)
 *    returns TaxFlags data in XML
 *
 *  getSmartHost()
 *    returns the SMART host
 *
 *  getBaseSmartUrl()
 *    returns base URL used to construct all the SMART cgi requests
 *
 *  getCostUrl()
 *    returns the url queried to get Item cost XML
 *
 *  getNameAndCostUrl()
 *    returns the url queried to get Item name and cost XML
 *
 *  getAssociateDataUrl()
 *    returns the url queried to get Associate data XML
 *
 *  getTaxFlagsUrl()
 *    returns the url queried to get Tag flag data XML
 *
 *  getClassName()
 *    returns class name
 *
 *  toString()
 *    returns string dump of object
