/**
* Generates getters for all fields, a useful toString method, and hashCode and equals implementations that check
* all non-transient fields. Will also generate setters for all non-final fields, as well as a constructor.
* <p>
* If any method to be generated already exists (in name - the return type or parameters are not relevant), then
* that method will not be generated by the Data annotation.
* <p>
* The generated constructor will have 1 parameter for each final field. The generated toString will print all fields,
* while the generated hashCode and equals take into account all non-transient fields.<br>
* Static fields are skipped (no getter or setter, and they are not included in toString, equals, hashCode, or the constructor).
* <p>
* <code>toString</code>, <code>equals</code>, and <code>hashCode</code> use the deepX variants in the
* <code>java.util.Arrays</code> utility class. Therefore, if your class has arrays that contain themselves,
* these methods will just loop endlessly until the inevitable <code>StackOverflowError</code>. This behaviour
* is no different from <code>java.util.ArrayList</code>, though.
