"Master" files are located on another GitHub site. So the code will always be current

Shiny app allows for the handling of new/different taxa from the MBSS official master taxa list in 3 ways.

• only MBSS (drop non-MBSS taxa)
• only user (ignore MBSS taxa list)
• add new (use MBSS taxa list for matching taxa but include new user taxa)

This is a handled with a pull down list prior to "calculation" on the Shiny app.
