I would like to use the number on the left as a key in a hash and use
the number on the right as the value pair to the key. Then print the
values for each hour that have the same key. Maybe this is a good
example for an array of hashes, but I not real sure how to begin. Any
help is greatly appreciated.

Below is the input data:

Hr 12
0001 2
0002 3
0003 1
Hr 13
0001 2
0002 3
0003 1
Hr 14
0001 2
0002 3
0003 1

Desired output below:

          12 13 14
0001    2   2  2
0002    3   3  3
0003    1   1  1
