Subject: Iterating through 2 fields for one hash, or array.

Hello,
I'm using Jamey Cribbs' KirbyBase as a database. The beauty of it is, of
course, that it's all pure Ruby. . . .

I need to iterate through a table with multiple fields. I've shown here
a very rudimentary example of the data that I'm working with.

   Cost Center    Page Count
     TMUS00           64
     ER0000           32
     DER000          128
     TMUS00           32
     DER000           64
     ER0000           10

I want to iterate through the table and create a hash, or an array, that
includes a single entry for each cost center and the total number of
pages counted for that cost center. So, I'd like to end up with
something like this below. I'm thinking I need a hash because the cost
center would be the key, with the page count being its value.

   Cost Center     Page Count
     TMUS00            96
     ER0000            42
     DER000           192

Thank you.
