# An arbitrary 'attribute' attachable to records.
#
# Gets support for arbitrary options via InheritableOptions. By default it
# has one option, +type+, but subclasses could extend for further options by
# overwriting +options_parameters+.
#
# By default, the +type+ options are managed via the +MenuOption+ class.

# Looks up the available +types+ for this attribute by fetching a
# titleized version of the class name from +MenuOption+.
#
# e.g.
#
# PhoneNumberAttribute.types
#
# is equivalent to:
#
# MenuOption.fetch_values('Phone Number')
