/**
 * <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>
 * &#064;TextChange(<b>R.id.helloTextView</b>)
 * void onTextChangesOnHelloTextView(CharSequence text, TextView hello, int before, int start, int count) {
 * 	// Something Here

 * &#064;TextChange
 * void <b>helloTextView</b>TextChanged(TextView hello) {
