Still not having added Fl_Tree and Fl_Table to Fluid, I remembered the plugin concept we had early on. It occured to me that writing plugins must not be difficult, and that FLTK already has everything needed. So here it is, a plugin implementation for FLTK. The MSWindows/Cygwin implementation is untested due to lack of a machine. The dynamic loading still needs a test implementation. Comments welcome.
