* UDP object
* LuaSocket toolkit
*
* The udp.h module provides LuaSocket with support for UDP protocol
* (AF_INET, SOCK_DGRAM).
*
* Two classes are defined: connected and unconnected. UDP objects are
* originally unconnected. They can be "connected" to a given address 
* with a call to the setpeername function. The same function can be used to
* break the connection.
