- Added Command line parser file - The sole responsibility is to parse
the command line and return a configData object.
- VideoManager is now a thin Main functions using the CommandLineParser
and then the VideoOrganizer
- Added Help in command line
- ConfigData now holds action that is configured in run time (will not
be present in file - and if will will be overridden in run time) -
According to the action the VideoOrganizer knows what to do.
- InitDir - prints only stuff necessary for action
