+/**
+ * `ngPlural` is an i18n directive that displays DOM sub-trees that match the switch expression
+ * value, or failing that, DOM sub-trees that match the switch expression's pluralization category.
+ *
+ * To use this directive, you must provide an extension of `NgLocalization` that maps values to
+ * category names. You then define a container element that sets the `[ngPlural]` attribute to a
+ * switch expression.
+ *    - Inner elements defined with an `[ngPluralCase]` attribute will display based on their
+ * expression.
+ *    - If `[ngPluralCase]` is set to a value starting with `=`, it will only display if the value
+ * matches the switch expression exactly.
+ *    - Otherwise, the view will be treated as a "category match", and will only display if exact
+ * value matches aren't found and the value maps to its category using the `getPluralCategory`
+ * function provided.
+ *
+ * If no matching views are found for a switch expression, inner elements marked
+ * `[ngPluralCase]="other"` will be displayed.
+ *
+ * ```typescript
+ * class MyLocalization extends NgLocalization {
+ *    getPluralCategory(value: any) {
+ *       if(value < 5) {
+ *          return 'few';
+ *       }
