/**
 * Creates a marker from each problem and adds it to the resource.
 * The marker is as follows://w w w .j a va2s. c  om
 *   - its type is T_PROBLEM
 *   - its plugin ID is the JavaBuilder's plugin ID
 *    - its message is the problem's message
 *    - its priority reflects the severity of the problem
 *    - its range is the problem's range
 *    - it has an extra attribute "ID" which holds the problem's id
 *   - it's {@link IMarker#SOURCE_ID} attribute is positioned to {@link JavaBuilder#SOURCE_ID} if
 *     the problem was generated by JDT; else the {@link IMarker#SOURCE_ID} attribute is
 *     carried from the problem to the marker in extra attributes, if present.
