Incremental release fixing several "cosmetic" issues:

1. adds travis CI and Zenodo DOI hooks.
2. improves code style consistency w/ lintr::lint_package() to improve readability.
3. fixes NAMESPACE warnings and notes generated by R CMD CHECK (though a few persist re: global variable bindings and some Roxygen tags).
