Subject: Major overhaul related to PySMI integration and Standard SNMP
 Applications API redesign: * MibVariable becomes ObjectIdentity and moves to
 pysnmp.smi.rfc1902 * ObjectType and NotificationType classes resempling
 corresponding MIB MACROs   implemented * SNMP Standard Applications and
 examples modified to support ObjectType   and NotificationType parameters
