Update GettingStarted.md
Fixed some missing cases from converting to HTML Dirichlet series.
Moved testing_math_classes
Ignore .DS_Store
Make --logfocus work.

logfocus didn't work before because the global logfocus variable wasn't
actually set, and also, even if it was going to be set it was going to
be set after the loggers were created.
