/**
* Represents all the display options that are supported by CLDR such as grammatical case, noun

* types of data. It replaces a DisplayContext[] as a method parameter.
*
* NOTE: This class is Immutable, and uses a Builder interface.
*
* For example:
* ```
* DisplayOptions x =
* DisplayOptions::builder().
* .setGrammaticalCase(UDISPOPT_GRAMMATICAL_CASE_DATIVE)
* .setPluralCategory(UDISPOPT_PLURAL_CATEGORY_FEW)
* .build();
