 * @description Represents a user input prompt with various configuration options.
 * @summary This class provides a flexible interface for creating and managing user input prompts.
 * It implements the PromptObject interface from the 'prompts' library and offers methods to set
 * various properties of the prompt. The class also includes static methods for common input scenarios
 * and argument parsing.
 *
 * @template R - The type of the prompt name, extending string.
 *
 * @param name - The name of the prompt, used as the key in the returned answers object.
 *
 * @class
 * @example
 * ```typescript
 * import { UserInput } from '@decaf-ts/utils';
 *
 * // Create a simple text input
 * const nameInput = new UserInput('name')
 *   .setMessage('What is your name?')
 *   .setInitial('User');
 *
 * // Create a number input with validation
 * const ageInput = new UserInput('age')
 *   .setType('number')
 *   .setMessage('How old are you?')
 *   .setMin(0)
 *   .setMax(120);
 *
 * // Ask for input and process the results
 * async function getUserInfo() {
 *   const answers = await UserInput.ask([nameInput, ageInput]);
 *   console.log(`Hello ${answers.name}, you are ${answers.age} years old.`);
 * }
 *
 * getUserInfo();
 * ```
