Some clarifications about submission announced in the lab :


1. Your library functions should be called from a main function 
   which should be in a separate file in the "source" sub-directory.
   The name of the file should be "main.c" or "main.cpp".

2. The header file should be named "quilt.h".

3. The executable should be named "quiltlib" and should be in the
   main directory. This is the same directory which contains the makefile.

4. The directory "testcases" contain quilts in matrix representation.
