Including source files

In addition to functions, we can also create multiple scripts and include them such that we can utilize any shared variables of functions.

Let's say we have a library or utility script that contains a number of functions useful for creating files. This script by itself could be useful or reusable for a number of scripting tasks, so we make it program neutral. Then, we have another script, but this one is dedicated to a single task: performing useless file system operations (IO). In this case, we would have two files:

1. io_maker.sh (which includes library.sh and uses library.sh functions)
2. library.sh (which contains declared functions, but does not execute them)

The io_maker.sh script simply imports or includes the
