All other field types extend FieldType providing the specific functionality
desired in each case.
The capabilities supported by each individual field type is decided by which
interfaces the field type implements support for. These individual
capabilities can also be checked via the supports*() methods.
Field types are the base building blocks of Content Types, and serve as
data containers for Content objects. Therefore, while field types can be used
independently, they are designed to be used as a part of a Content object.
Field types are primed and pre-configured with the Field Definitions found in
Content Types.
