Paper: Frequentism and Bayesianism: A Python-driven Primer (Jake VanderPlas)

This is the final version – ready to be reviewed.
Minor/stylistic suggestion: while I appreciate the urge to be complete, you might consider removing the ``(we'll assume for now that the star's flux does not vary with time)`` and ``(delta functions aside)`` parentheticals.  They strike me as a bit distracting without really adding too much content.  For the former, you might just replace it with ``a given non-variable star`` or a similar non-parenthetical statement.
