Structs

This is a custom type which acts a wrapper around clap’s Arg struct and adds some extended custom functionality.

All arguments can have three types - POSITIONAL, SWITCH and FLAG. This enum takes care of handling logic for these three types.

all_args_and_flags	This function takes a vector as an argument and pushes all the arguments for the app into it. This can be later used to build the command line application.
app	This sets some basic metadata about our command line application, such as `help`, `version` etc, and then attaches all the relevant arguments to it.
