Zoo database
A simple database containing 17 Boolean-valued attributes describing animals. The "type" attribute appears to be the class attribute.
Notes:
* I find it unusual that there are 2 instances of "frog" and one of "girl"!
* feature 'animal' is an identifier (though not unique) and should be ignored when modeling
