/**
 * @class
 *
 * Returns a connection to a MySQL server or a specific database.
 *
 * For connection the MySQL++ library is used. MySQL++ throws exceptions
 * in case of errors, e.g. connection timeout.<P>
 *
 * Note that although the object is created with 'new' and there
 * is a 'delete' is JavaScript, it will not call any kind of
 * destructor. To close a Subscription you have to explicitly call
 * the close() member function. 'delete' in JavaScript is only
 * to remove a property from an Object.
 *
 * @param {String} database
 *    The databse argument is of this form (optional parts ar given in brackets):<br>
 *    <tt>user:password@server.domain.com[:port]/database</tt>
 *
 * @throws
 *    <li> If number or type of arguments is wrong
 *    <li> If no connection could be opened, an exception with the reason is
 *    thrown.
 *
 * @example
 *    var db = new Database("thomas@sql.at-home.com/database");
