# Represents a Field in a Vocabulary
# This is an abstract class.  The concrete class must implement:
#
#     fromString() -- Returns contents from a string without input processing
#     contents() -- Returns the contents of the field unaltered
#     raw()      -- Returns a string of the contents unaltered
#     copy()     -- Copies the contents from a field if it is assigned
#     eql?()     -- Returns true if the contents are eql? to the passed contents
