There are 2 hash tables:
%hashCellID;
%hashCellname;

Each key ($lv) of the hashCellID hash table points to an array of cellID's. Presumably as new cellID's are seen for an lv, they are pushed onto the array for that lv.
push (@{$hashCellID{$lv}} , $cellID);

At the end of the day, each lv in the hashCellID table will correspond to an array of cellID's of unknown length. And this array can be printed like: print "@{$hashCellID{$lv}}\n";

To find out the keys of the hashCellID hash: 

foreach my $lv (keys %hashCellID)
{
   print "$lv = @{$hashCellID{$lv}}\n";
}

The hashCellname just counts how often a particular cellname has occurred.
$hashCellname{$cellname}++;
This is basically a histogram count of cellnames. 
foreach my $cell (keys %hashCellname)
{
   print "$cell count = $hashCellname{$cell}\n";
}
