Bad shell arguments initialization

[RDCH106]

The file main.go overwrites the arguments with no checks:

        httpPort := DefaultHTTPPort
	computerFilePath := DefaultComputerFilePath

	// Start Processing Shell Arguments or use Default Values defined i const.go
	httpPort, computerFilePath = processShellArgs()

	// Process Environment Variables
	httpPort, computerFilePath = processEnvVars()

The result of the evaluation o the piece of code is that the environment variables are used or default values are used. The shell arguments always will be overwritten.
