BUG: setitem fails on mixed-type Panel4D
ENH: provide a null_counts keyword to df.info() to force showing of null-counts
BUG: fix reflected comparison operations for Categorical

By the time the comparison gets dispatched to _cat_compare_op, the first
argument becomes zerodim array and no longer passes isscalar test.

ENH: add pd.lib.item_from_zerodim to extract values from zerodim arrays

ENH: make pd.lib.isscalar detect pd.Period, datetime.date and datetime.time

BUG: Bug in Panel indexing with a list-like (GH8710)
ENH: add Index.is_monotonic_decreasing and Index.is_monotonic_increasing

Index.is_monotonic will have a performance degradation (still O(n) time) in
cases where the Index is decreasing monotonic. If necessary, we could work
around this, but I think we can probably get away with this because the fall-
back options are much slower and in many cases (e.g., for slice indexing) the
next thing we'll want to know is if it's decreasing monotonic, anyways.

see GH7860

also: NaN and NaT imply not monotonic
