/**
 * :package: **botbuilder-choices**
 *
 * High level function for recognizing a choice in a users utterance. This is layered above the
 * `findChoices()` function and adds logic to let the user specify their choice by index (they can
 * say "one" to pick `choice[0]`) or ordinal position (they can say "the second one" to pick
 * `choice[1]`.) The users utterance is recognized in the following order:
 *
 * - By name using `findChoices()`.
 * - By 1's based ordinal position.
 * - By 1's based index position.
 *
 * **Usage Example**
 *
 * ```JavaScript
 * const { recognizeChoices } = require('botbuilder-choices');
 *
 * const choices = ['red', 'green', 'blue'];
 * const utterance = context.activity.text;
 * const results = recognizeChoices(utterance, choices);
 * if (results.length == 1) {
 *     await context.sendActivity(`I like ${results[0].resolution.value} too!`);
 * } else if (results.length > 1) {
 *     const ambiguous = results.map((r) => r.resolution.value);
 *     await context.sendActivity(ChoiceFactory.forChannel(context, ambiguous, `Which one?`));
 * } else {
 *     await context.sendActivity(ChoiceFactory.forChannel(context, choices, `I didn't get that... Which color?`));
 * }
 * ```
 * @param utterance The text or user utterance to search over. For an incoming 'message' activity you can simply use `context.activity.text`.
 * @param choices List of choices to search over.
 * @param options (Optional) options used to tweak the search that's performed.
