This is an S4-using package but missing a dependence on 'methods'.
To run R CMD check the package has to load under minimal conditions, e.g.
R_DEFAULT_PACKAGES=NULL R
...
> library(foo)
should work. 'methods' is quite expensive to load, and so is only used in
checking if explicitly requested.

Depends: methods
Package stats4 is provided in part as an example of a small S4-using
package for people to copy.
