 * Description of a Java problem, as detected by the compiler or some of the underlying

 * A problem provides access to:
 * <ul>
 * <li> its location (originating source file name, source position, line number), </li>
 * <li> its message description and a predicate to check its severity (warning or error). </li>
 * <li> its ID : an number identifying the very nature of this problem. All possible IDs are listed
 * as constants on this interface. </li>

 * Note: the compiler produces IProblems internally, which are turned into markers by the JavaBuilder
 * so as to persist problem descriptions. This explains why there is no API allowing to reach IProblem detected
 * when compiling. However, the Java problem markers carry equivalent information to IProblem, in particular
 * their ID (attribute "id") is set to one of the IDs defined on this interface.
