* New print format for tibbles and data.tables
#### Changed
* Support for older R versions, only R 3.1.3 or later is needed
* Support for old R versions, only R-3.0.0 (April 2013) or later is needed
* Renamed dataset `ablist` to `antibiotics`
* Renamed dataset `bactlist` to `microorganisms`
* Added more microorganisms to `bactlist`
