Modified Files:
callbacks.c cibio.h io.c main.c
Log Message:
Implement an option (-f) that instructs the CIB to:
- read the (complete) CIB from disk before an operation
- write the (complete) CIB to disk after each operation
- deallocate the in-memory copy of the CIB after each operation
Aids debugging of memory leaks and should never be used in production
