Create a enter_array verb

[jeremystan]

I often find myself doing this:

... %>% enter_object("array") %>% gather_array %>% ...

Create a function, enter_array, that combines the two steps into one. The interface should be similar to gather_array, with the exception that there is an extra argument that specifies the key name for the array object, and the array.index should default to just paste "index" onto that name.

Thus, the above code becomes:

... %>% enter_array("array") %>%  ...

Not so sure about this anymore, enter_array would need to take both the key name to find the array, and the column name to create, which is probably confusing. Perhaps best to leave this as is.
