Initial checkin for scope

[Jeff Bailey]

I have made the initial checkin of ``scope''.  This will be an
SNMP-based analysis of the remote system.

Currently, I have a perl script that detects which systems are
attached to given ports on a bridge.  It successfully identifies
*which* ports are bridge ports, fetches their names, and tracks which
MAC addresses are associated with them.

The next step is to build a single object to represent a given system.
Then I can begin resolving the MAC Addresses to IP addresses.  With
that, I can chain to other systems, and build a network view.

If you feel like playing with this, create a "community.txt" file with
the community string, and a "host.txt" with the ip address.  You also
need the net-snmp programs on your system.

Here's some sample output from the perl script.

Number of ports: 24
FastEthernet0/1
FastEthernet0/2
  Hex: 00 E0 1E 3E AD 21 
FastEthernet0/3
  Hex: 00 60 47 80 C0 DD 
FastEthernet0/4
  Hex: 00 50 73 1D CB 8B 
FastEthernet0/5
