underscore issue

[arlin]

from the manuscript review: consider cases in which user inputs may have underscore in place of space, as in "Homo_sapiens".

• Identify when this might happen.
• consider how to address it
• make a plan and execute the plan

[arlin]

we are going to punt on this, passing the issue to Global Names. When they implement the option to treat underscores as spaces, we will allow that also.
