  1. fix: Improve command line argument handling 

    Handle arguments passed into the program through <stdin>.
Partially conforms to the GNU Argument Syntax:
https://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html

Flags are handled first before the arguments.
If an flag passed is incorrect, then an error is returned.
Flags handled as of now include:
	-h, --help: For printing help messages
	-m, --msaada: Kuonyesha usaidizi
	-v, --version, -t, --toleo: Showing the version
Previous implementation supported flags like:
	--docs (should be an argument)
	-docs
	-version
	-msaada
	-help
	-toleo
This flags do not conform to the GNU Argument Syntax.
If any of this flag is passed, then the program prints the information and exits.

Arguments processed after the flags.
Arguments supported as of now are that of filename.
Any of the argument passed is treated as a filename and may fail if not one.
Prevoius implementation allowed arguments like:
	version
	msaada
	help
	v
This are not supported as of now.

Error messages are printed to stderr instead of stdout.
