Two little things on summaries

[mjohnson11]

1 - "entires -> entries"
2 - I interpret "unique entries" to mean singletons (i.e. values that only appear in one row). This instead reports the number of unique values in the column. Since that value is also given up at the top before the summary, I think singletons would be more useful here (and the "XX out of XX non-null rows" makes it seem like maybe this is what you were going for too?)

Thanks for finding spelling error! I think singletons is great idea since youre right this info is a big redundant with the unique values right now.

My code interpretation of a singleton would be all the values where the value_count is exactly 1

Yeah, that's my interpretation too!
