  sc_buffer_edge_reset.cpp -- Test sc_buffer<bool> edge events and reset

  Original Author: Philipp A. Hartmann, OFFIS, 2013-10-12

 -----------------------------------------------------------------------------

 This test checks the functionality of the pos(), neg() event finders and
 the async_reset_signal_is functionality, if the target port is bound to
 an sc_buffer instead of an sc_signal.
