+/**
+ * Class REPORTER
+ * is a pure virtual class used to derive REPORTER objects from.
+ *
+ * The purpose of the REPORTER object is to offer a way for a procedural function
+ * to report multiple errors without having to:
+ * <ul>
+ * <li> know too much about the caller's UI, i.e. wx. </li>
+ * <li> stop after the first error </li>
+ * </ul>
+ * the reporter has 4 severity levels (flags) tagging the messages:
+ * - information
+ * - warning
+ * - error
+ * - action (i.e. indication of changes - add component, change footprint, etc. )
+ * They are indicators for the message formatting and displaying code,
+ * filtering is not made here.
