+ * Signal is a template type providing an interface for arbitrary callback
+ * lists.
+ * A signal type needs to be declared with the function signature of its
+ * callbacks,
+ * and optionally a return result collector class type.
+ * Signal callbacks can be added with operator+= to a signal and removed with
+ * operator-=, using
+ * a callback connection ID return by operator+= as argument.
+ * The callbacks of a signal are invoked with the emit() method and arguments
+ * according to the signature.
+ * The result returned by emit() depends on the signal collector class. By
+ * default, the result of
+ * the last callback is returned from emit(). Collectors can be implemented to
+ * accumulate callback
+ * results or to halt a running emissions in correspondance to callback results.
+ * The signal implementation is safe against recursion, so callbacks may be
+ * removed and
+ * added during a signal emission and recursive emit() calls are also safe.
+ * The overhead of an unused signal is intentionally kept very low, around the
+ * size of a single pointer.
+ * Note that the Signal template types is non-copyable.

+    already has C++11 std threading classes implemented, based on pthreads.             \
+    It is likely that you will get class redefinition errors below, and unfortunately   \
+    this implementation can not be used standalone                                      \
+    and independent of the system <mutex> header, since it relies on it for             \
+    std::unique_lock and other utility classes. If you would still like to use this     \
+    implementation (as it is more lightweight), you have to edit the                    \
