added dispEntries and dispEntryDetail testing functions
Foundations for build_tree_postorder() in place.
Continued implementing build_tree_postorder(). Now completes but needs
more work to properly populate information into entries[].
Progressed with build_tree_postorder - now able to properly traverse.
Postorder now properly computes depth for all directory paths given.
Cleaned up in preparation to compelete postorder implementation
Implemented memory allocation and population of direct children
Completed command line integration and clean-up.
Updated man page.
Updated make file for gtk/cairo - foundations of gui()
Merge branch 'master' of github.com:andeh575/duvis
Revised Makefile for gtk/cairo - foundations of gui()
gui() now properly accesses entries.components and .size for drawing
Finally figured out how to pass variable window dimensions from gtk to cairo
Corrected an error in Makefile after adding GTKFLAGS
Attempt to simplify/fix/speedup postorder traversal
Experimenting with recursion
Reworked postorder recursion - pushing to test on larger platforms
did some code housekeeping preparatory to changes
changed build_tree_postorder to take ending index plus one; refactored some code
