/**
* <p>
* This annotation is intended to be used on methods to receive events defined
* by
* {@link android.text.TextWatcher#onTextChanged(CharSequence s, int start, int before, int count)}
* when the text is changed on the targeted TextView or subclass of TextView.
* </p>
* <p>
* The annotation value should be one or several R.id.* fields that refers to
* TextView or subclasses of TextView. If not set, the method name will be used
* as the R.id.* field name.
* </p>
* <p>
* The method MAY have multiple parameter :
* </p>
* <ul>
* <li>A {@link android.widget.TextView} parameter to know which view has
* targeted this event</li>
* <li>An java.lang.CharSequence parameter to get the modified text.</li>
* <li>An int parameter named start to get the start position of the modified
* text.</li>
* <li>An int parameter named before to know the text length before
* modification.</li>
* <li>An int parameter named count to know the number of modified characters.</li>
* </ul>

*
* Examples :
*
* <pre>
* @TextChange(<b>R.id.helloTextView</b>)
* void onTextChangesOnHelloTextView(CharSequence text, TextView hello, int before, int start, int count) {
* // Something Here
* }
