jp (input): input command first draft: this is an experimental command to use external data as input arguments. A series of data is used (only CSV is implemented so far), and it is used to fill argument of a command according to a sequence. The sequence is given using input arguments, with types corresponding to the data found (short option, long option, stdin). e.g. if a CSV file has row with 3 columns, we can say that column 1 is subject (long option), column 2 is body (stdin), and column 3 is language (short option -l). A filter can be used after each option type, to transform read value. Finally a static part is used to have the main command and non dynamic arguments to use.
