Add uniqueColumn derived method #24

Closed iros closed 12 years ago

iros commented 12 years ago

We seem to constantly need a set of unique values in a dataset.

iros commented 12 years ago

Instead support:

// returns full column, all rows
dataset.column('city');
// returns a dataset without the excepted columns
dataset.column({ except : 'timestamp' })
// returns a new dataset comprised of unique values in the specified column
dataset.columns({ unique : 'city'});

How about 

dataset.column('city', { unique : true });

Will fix for #156.
