◆ ParseOptions()

void ParseOptions	(	int	ac,

	)

Parses program options from the command line or another source and stores the values in member variables.

It also checks the validity of the parsed parameters. Throws a cxxopts exception if parsing fails or an armnn exception if parameters are not valid.
