Remove Duplicates (just by Index). #309

This is super helpful if one has a data frame indexed by date.

Also, as a statistical thing, it would be nice to count the number of duplicates in a Data Frame too.

I actually already had the code for remove_duplicates() with index column by itself. I merged it to master. For the count look at value_counts(). See if that satisfies your requirements.
