+/**
+ * TReCaptcha2 class.
+ *
+ * TReCaptcha2 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 setSecretKey SecretKey}
+ * and {@link setSiteKey SiteKey} 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 TReCaptcha2Validator} 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:TReCaptcha2 ID="Captcha"
+ * SiteKey="..."
+ * SecretKey="..."
+ * />
+ * <com:TReCaptcha2Validator ControlToValidate="Captcha"
+ * ErrorMessage="You are challenged!" />
+ * </code>
