Compile fill with the command
gcc -lm -o fill fill.c
******
The fill program takes two command line options. Invoke it as

fill file1 file2

file1 is the name of the input file. file2 is the output file name. If 
file2 is not present, output will be sent to "file1.mem"

The input file should be in the same format as the Data/out file generated
for the multi_slalom search. In particular if from the McBilliards 
main directory you type
C2/fill Data/out Memory/fill
the program will read the search data for the multi_slalom search from 
Data/out and generate a Memory style file that can be plotted from 
McBilliards. 

I included two test files, "out_fill" and "out_fill2" in the C2/example_out 
directory. From the C2 directory the program can be tested as
./fill example_out/out_fill
and
./fill example_out/out_fill2

The first test should generate a test.mem file with one tile.
The second test should generate a test.mem file with 2 tiles.
