Improve report

[see24]

I think the report can be improved to be more effective. My suggestions are as follows:

• Include a brief summary about CCVI to support interpretation of the report by users unfamiliar with CCVI. Suggestion of what to include outlined in this doc
  • At least explain what the reported score indicates (ex: Moderately Vulnerable - Abundance and/or range extent within geographical area assessed likely to decrease by 2050)
• Have both maps on the same page (page 2)
• Make use of headers, sub-headers, and line breaks (especially on page 1)
• Lighten colors used to highlight the score (very light)
• Add date of assessment to report, name of assessor, and geographic areas assessed to report (info from Species Information)

Improve the progress bar so it actually moves more as the report is being processed.
