stand_list = {
        'classes': [
            ('Douglas-fir', 6, 14, 191),
            ('Douglas-fir', 14, 18, 7),
            ('Western hemlock', 14, 18, 5),
            ('Western redcedar', 14, 18, 5),
        ]
    }

For each stand list class, we are looking for a 4-item list or tuple containing:

Species
Low range of diameter class (in)
High range of diameter class (in)
Trees per acre

The diameter classes are matched as follows: low <= diameter < high

Suggested diameter classes could be incorporated client-side (based on email from David Diaz, Tue 2/5/2013 12:00 PM)

Seedlings 0-2"
Sapling 2-6"
Small Trees 6-12"
Large Trees 12-30"
Very Large Trees 30-??"
