// Widget type header file for the Fast Light Tool Kit (FLTK).
//
// Each object described by Fluid is one of these objects.  They
// are all stored in a double-linked list.
//
// There is also a single "factory" instance of each type of this.
// The method "make()" is called on this factory to create a new
// instance of this object.  It could also have a "copy()" function,
// but it was easier to implement this by using the file read/write
// that is needed to save the setup anyways.
