 CLEAN UP
-Write a class that parses /proc and not ifconfig
 udchcp needs to output the dhcp information so interfaces can read it
 interfacesetupimp really doesn't need a interface* pointer
 Possible other modules to write: ppp, ipsec, bluetooth, ipchains
 PPP module needs to scan pppd.tdb to see what is currently active
 WLAN - add possiblity to input text or hex without knowing "s:"
+Interface setupimp needs to use kernel calls.
