headers.h

/* This header contains
 | All function declarations from each and every source file
 | Necessary inclusions of std/third-party libraries
 | Every macro
 | 
 | Un-included libraries have their stuffs declared in libheader.h
 | NOTE that stdio.h is compulsory unless you want to suffer
 |      warnings during compilation. Another reason of keeping
 |      stdio.h was the struct FILE couldn't be defined in
 |      libheaders.h file.
