Pivot capability about eel-sdk HOT 4 CLOSED

I've never really understood pivot tables. It seems you're replacing the
column names with values of a different column, so in this case the type of
drinks are the new column headers. Is it sufficient to just say
frame.pivot(columnName), or do you need to specify two, and if two, why.

Imagine you have a schema : quarter - product - sales with data

("quarter1", "wine", 100)
("quarter1", "beer", 220)
("quarter1", "coffee", 550)
("quarter2", "coffee", 5)

And you want to pivot by product and sales - with newschema = "wine"
, "beer" , "coffee" defaultvalue=0 resulting into data

quarter wine beer coffee
quarter1 100 220 0
quarter2 0 0 5

Also be able to unpivot the data

This might have to live in an algo module as pivot requires all (?) / some (?) data in memory at once.
