class Category extends AnyRef
The class Category represents categories of experiences in the GoodStuff diary
application. A single category contains zero or more experiences that are similar
in some way and are purchased in units of the same kind. A category object could
be used represent hotel experiences, for instance, or wines the diarist has tasted.
A category object has a mutable state: A newly created category has no experiences
yet; experiences must be added to it using the addExperience method.
