Change title from "Find Unique Values In Pandas Dataframes" to "...Columns"

[mborus]

Hi,

would you mind changing the title of

https://chrisalbon.com/python/data_wrangling/pandas_find_unique_values/

to "Find Unique Values In Pandas Dataframe Columns"

Currently it comes up a hit for the google question on how to find unique values within (the whole) DataFrame - which is a different problem (I googled for that to find out if there's a better way than collecting the uniques of each column via a set comprehension)

Thanks
