Missing newline in 'show' method for ENMevaluation objects

[plantarum]

I admit this is a trivial issue!

When printing an ENMevaluation object, the final line doesn't have a new line. That leaves the prompt at the end of that line, and makes my obsessive-compulsive eyes twitch.

Adding a \n should resolve this:

cat("Refer to ?ENMevaluation for information on slots.\n", sep = "") 

Thanks for your work, this package is invaluable!
