Examples of methods for determining the directory path where our executable resides.

-	The `github.com/kardianos/osext` package is used for reference. The other methods
	will require that the executable is located within the OS search path.

-	The first alternative utilizes `exec.LookPath` to find the executable within the
	OS search path. This method depends on the `os`, `os/exec`, and `path` packages.

-	The next method defines a local function to look for the file named in `args[0]`
	in the directories listed in the `PATH` environment variable. This method depends
	on the `os` and `strings` packages.
