New Features
- 1. Addition of a credibility index. This is a quick warning of results
that are of questionable validity.
- 2. Separate lists for regional and species-specific trends. These are
easier to search.
- 3. A table of comparative results of the earlier year's analysis, and
a comparison of results that do not include "new routes." This allows users
to see the consequences of adding routes that do not have historical (e.g.,
pre-1992) data.
