usage clarifications for causal-cmd (

[espinoj]

When I run the causal cmd without any arguments, I don't see all of the usage details. Is it possible to change he default usage code to indicate that "--algorithm xxx" should be specified for usage details on algorithm xxx?

Also remove old json output feature. Keep the new one.

For the first issue, I don't see what the problem is. I do see usage detail when running causal-cmd without any argument. See below. Can you please clarify? java -jar causal-cmd-0.2.0.jar

usage: java -jar causal-cmd-0.2.0.jar --algorithm <arg> | --simulate-data <arg>  [--version]
    --algorithm <arg>       FGESc, FGESd, FGESm-cg, GFCIc, GFCId, GFCIm-cg
    --simulate-data <arg>   sem-rand-fwd, bayes-net-rand-fwd, lee-hastie
    --version               Show software version.
Additional parameters are available when using --algorithm <arg> or --simulate-data <arg>.

For the second issue, yes. We can remove any unused switch. Will work on this.

@kvb2univpitt Decision is to hide --json

[kvb2univpitt]

@espinoj To keep the code clean, can we just completely remove it? We can always put it back if we ever need it, since we tagged previous versions of it.

harry still needs it but for general users it is confusing

[kvb2univpitt]

We are using the Apache CLI library to parse the command line inputs. If we remove the json option to hide it from the user, the Apache CLI will scream "Unrecognized option" if Harry tries to pass it in.

@espinoj @harryhoch Ok. I created a method to work around that. --json switch is now hidden from the user but still available.
