BLD: initial coveralls config
More and more! weird coverage bug though...
MAINT: pass a whole row/column to filtering function
Trying to return a sparse vector fast.
ENH: Allow user to choose between a fast and memory efficient
filtering and full rows/cols
MAINT: keep only one outer if.
MAINT: actually there isn't a significant performance difference if the if
is inside the loop.
MAINT: remove unused import
MAINT: match parameter name with meaning
TST: add test for compressed_vals = False
BUG: Table.sort_order didn't retain Table.type

Calling Table.sort_order on a Table would return a seemingly identical
table the only difference was that the returned value would have a
Table.type of None regardless of whatever that inital value was.

I've also added an Examples section to this method.
ENH: We can actually return full vectors and just pay a ~50% speed penalty
(which seems OK given that it was several 100s faster than the pure python
version)
Remove compressed_vals API
TST: remove test for deleted parameter
MAINT: Add comment to clarify loop
