trying to get travis working for the subdirectory setup
the file is really called ./travis-tool.sh
really, the first copy works but the second fails?
try dropping EML from suggests, as install_github refuses to ignore it
step by step here. forgot rJava binary
now I forgot github dataonelibs
travis just checks that we can install and load the package, since further testing does not make sense without authentication
run check without tests or examples
use up-to-date options
skip library load test
it's ---no-build-vignettes now, --no-vignettes is deprecated
change install instructions from CRAN to Github for now, and add travis badge
Merge pull request #44 from ropensci/master

Add travis integration, thanks to @cboettig.
