Tim,
Thanks again for the detailed thoughts. It looks like your approach is
structured in a way that should handle what I'm looking for, and provide
a framework for future expansion. I went ahead and implemented it in,
and am trying to resolve an issue now (NoMethodError (undefined method
`values_at') for `search_array_with_hashes' but I'll let you know once
it gets working.
Cheers!
