Add exportMethods(plot) & exportClasses(ModelEvaluation) to NAMESPACE

[SimonDedman]

Hi Robert, hope you're well. I was wondering if it would be possible for you to add

exportMethods(plot)
exportClasses(ModelEvaluation)

to dismo's NAMESPACE?

I'm trying to run a function which uses various dismo functions including evaluate, and then plotting the resultant object, but it's suddenly started failing with

plot: Error in as.double(x): cannot coerce type 'S4' to vector of type 'double'

I believe this may be because dismo doesn't export its plot method of ModelEvaluation class, so when run in a function, plot defaults to base graphics, and thus expects x to be a double rather than a ModelEvaluation class.

Thanks in advance, and thanks for all of your work on this!
