//
// Class which allows a cookie file to be imported in memory
// for ht://Check and ht://Dig applications.
//
// The cookie file format is a text file, as proposed by Netscape,
// and each line contains a name-value pair for a cookie.
// Fields within a single line are separated by the 'tab' character;
// Here is the format for a line, as taken from http://www.cookiecentral.com/faq/#3.5:
// 
// domain - The domain that created AND that can read the variable.
// flag - A TRUE/FALSE value indicating if all machines within a given domain
//	can access the variable. This value is set automatically by the browser,
//	depending on the value you set for domain.
// path - The path within the domain that the variable is valid for.
// secure - A TRUE/FALSE value indicating if a secure connection with the
//	domain is needed to access the variable.
// expiration - The UNIX time that the variable will expire on. UNIX time is
//	defined as the number of seconds since Jan 1, 1970 00:00:00 GMT.
// name - The name of the variable.
// value - The value of the variable.
//
