Two methods were added to find the netmask of an IP address, both are based in the findAddressInTree() method found on the Reader struct.

Netmask() returns the netmask value along with any errors found. Heavily based on findAddressInTree().
LookupOffsetWithNetmask() adds an additional return value with the netmask value.

Both methods are suited for NS1's needs but we think they may be useful.

59 accomplishes this same goal in a bit different way. I am closing in favor of that.
