Archiving data structures

README: this file

FEV.h
FEVtypes.h:  define particular struct types for silly-simple
              graphical representation: faces, edges, vertices.
              a face is in a circ. list of faces, each of which has
              a circ. list of edges, each of which has two vertices,
              each of which has a matrix.

FEV.c:  a ton of hastily-written maybe-useful utilities for creating,
	printing, reading... FEV structs.  Lots of annoying debugging
	output: should have " if (DEBUG)" in front of all printfs.
  
tetra.c:   produces a pointer to a legal tetrahedron 
           linked (non-printable) data structure.

struct_to_file.c:  INCOMPLETE 
             does the work to create printable structs from
             a VEF struct and in a recursive, depth-first way
            to visit the structs, convert them,  and print the
            resulting p-structs out.  Argument is a "head pointer"
            into the data structure.

struct_to_file_format:  CB's format for an archived (printed) data
			structure.  In place of pointers, ints
                         implicitly refer to associated arrays of
                         pointers to (non-printable) structs to be
                         constructed and linked by pointers.

file_to_struct.c:  INCOMPLETE
                a  two-pass algorithm to recreate a linked
		   data structure from an archived printable one:
                   returns the original "head pointer".

matrix code:  all we need (creation and printing) is in the ../matrix directory.

struct_file_format:  format for disk file with printed out struct
information,  either for test input or generated by writing out
a the printable form of an initially linked structure.  E.g. the next
two files are in this format.

psfile_in.data:  very simple nonsense FEV structure file for debugging. 

psfile_out.data: the file I get by running file_to_struct 
		 on psfile_in.dat and running
		 struct_to_file on the result (a get_put_get) scenario,
		 complentary to the put-get_put scenario of the assignment).

put_get_put.c:  creates, archives, reconstructs, rearchives a tetrahedron.

Maketest: produces the executable for demonstrations like the above.

mini_example/:  was meant to help, but may just be waste of your
		time.   Feel free to ignore.
