Option to enter column name of dataframe as formula terms

[shounak112358]

I was trying to use pyGAM as I don't like changing my interface from Python to R. However, 'mgcv' package of R gives me the opportunity of devising the terms as the column names directly, and see their impact on my model (got more than 200 variables). It could be great if you guys can do something similar so I don't have to go through finding which of the variables have what kind of impact on my models.
