* ### Synopsis
*
* var handle = memcached.connect(servers);
*
* Create a connection to the specified memcached servers.
*
* The servers argument is a comma separated list of memcached servers. The server names are of the form <code>hostname[:port]</code>.
*
* @param {string} servers - comma separated list of servers
* @return {object} handle - opaque handle used for other memcached methods, or false if an error occurred.
