/**
 * TReCaptcha class.
 *
 * TReCaptcha displays a reCAPTCHA (a token displayed as an image) that can be used
 * to determine if the input is entered by a real user instead of some program. It can
 * also prevent multiple submits of the same form either by accident, or on purpose (ie. spamming).
 *
 * The reCAPTCHA to solve (a string consisting of two separate words) displayed is automatically
 * generated by the reCAPTCHA system at recaptcha.net. However, in order to use the services
 * of the site you will need to register and get a public and a private API key pair, and
 * supply those to the reCAPTCHA control through setting the {@link setPrivateKey PrivateKey}
 * and {@link setPublicKey PublicKey} properties.
 *
 * Currently the reCAPTCHA API supports only one reCAPTCHA field per page, so you MUST make sure that all
 * your input is protected and validated by a single reCAPTCHA control. Placing more than one reCAPTCHA
 * control on the page will lead to unpredictable results, and the user will most likely unable to solve
 * any of them successfully.
 *
 * Upon postback, user input can be validated by calling {@link validate()}.
 * The {@link TReCaptchaValidator} control can also be used to do validation, which provides
 * server-side validation. Calling (@link validate()) will invalidate the token supplied, so all consecutive
 * calls to the method - without solving a new captcha - will return false. Therefore if implementing a multi-stage
 * input process, you must make sure that you call validate() only once, either at the end of the input process, or
 * you store the result till the end of the processing.
 *
 * The following template shows a typical use of TReCaptcha control:
 * <code>
 * <com:TReCaptcha ID="Captcha"
 *                 PublicKey="..."
 *                 PrivateKey="..."
 * />
 * <com:TReCaptchaValidator ControlToValidate="Captcha"
 *                          ErrorMessage="You are challenged!" />
 * </code>
