What to do with objects that have more than one class? #87

This if is technically wrong, and will warn if the object has more than one class. For instance:

> class(data.table::data.table())
[1] "data.table" "data.frame"

Should everything that is a data frame be converted to a data table (any(...)), or should only "pure" data frames be converted to data tables (all(...))?

Implementing the second option as part of #76, still open for discussion.

The commit is bad, should be any instead of all (or an inherits() call).
