Description
 This widget was designed to add the functionality of compressing and
aligning widgets.
If type() is FL_HORIZONTAL all the children are
resized to the height of the Fl_Pack, and are moved next to
each other horizontally. If type() is not FL_HORIZONTAL
 then the children are resized to the width and are stacked below each
other.  Then the Fl_Pack resizes itself to surround the child
widgets. 
This widget is needed for the Fl_Tabs.
 In addition you may want to put the Fl_Pack inside an 
Fl_Scroll. 
Methods
 Creates a new Fl_Pack widget using the given position, size,
and label string. The default boxtype is FL_NO_BOX.
 The destructor also deletes all the children. This allows a
whole tree to be deleted at once, without having to keep a pointer to
all the children in the user code. A kludge has been done so the 
Fl_Pack and all of it's children can be automatic (local)
variables, but you must declare the Fl_Packfirst, so
that it is destroyed last.
 Gets or sets the number of extra pixels of blank space that are added
between the children.
