This make the table output good looking, and allows users to click table
headings to sort data by column without rerunning the analysis.
Unfortunately this change is breaking change, meaning the old CSS tags are
no longer supported, nor partial html output that printed only the table.

The problem is, that you simply count all lease occurrences in
dhcpd.leases, but only the last ones for each ip address are
valid. The lease file is more like a logfile of what has been
done, than a real database. To fix the counting issue, I'm using
a single hash (from uthash.h [1]) for the counting. This way
only the last lease entry for each IP gets into my counting
structure.
When you remove the duplicates in prepare_data(), you don't have
the information anymore, if the active lease entry or the free
lease entry came last. Simply deleting each ip from the touches
array, that is already in the leases array, gives you a big
chance to count wrong. Another way of fixing this would be to
not only store the ips in your arrays, but a structure containing
the ip and a global lease entry counter. Then you could delete
all entries except for the latest.
