/**
 * FormetterOptions holds information that affects the way a formatter
 * renders its output.
 *
 * There are three places where a formatter might get options from:
 *
 * 1. Configuration associated with the command that produced the output.
 *    This is passed in to FormatterManager::write() along with the data
 *    to format.  It might originally come from annotations on the command,
 *    or it might come from another source.  Examples include the field labels
 *    for a table, or the default list of fields to display.
 *
 * 2. Options specified by the user, e.g. by commandline options.
 *
 * 3. Default values associated with the formatter itself.
 *
 * This class caches configuration from sources (1) and (2), and expects
 * to be provided the defaults, (3), whenever a value is requested.
