* call-seq:
 * LDAP.mod(mod_type, attr, vals)  => LDAP::Mod
 * Create a new LDAP::Mod object of type, +mod_type+. This is most commonly
 * servers may offer extension types. 
 * +attr+ should be the name of the attribute on which to operate, whilst
 * +vals+ is an array of values pertaining to +attr+. If +vals+ contains
 * binary data, +mod_type+ should be logically OR'ed (|) with
 * LDAP::Mod objects can be passed to methods in the LDAP::Conn class, such as
 * Conn#add, Conn#add_ext, Conn#modify and Conn#modify_ext.
