Generator CLI args in docs

"""In the case where we pass something along the command line, the tool looks for source files in the argument if it is a directory or tries to interpret the argument as source of it is a file"""

From #18 (--output-path, --make-dir, --quiet, --verbose:

Added two command-line (and metadata fields) to allow control over output location. Command-line arguments are used in the case where both are given

• --output-path allows a parent path for generated questions to go (alias -o)
  • default: next to the source file
  • metadata respective field: "output-path" : str
  • an empty value for this field uses the default value
  • e.g. course/question_src_files/ $ generate_fpp.py --output-path ../questions/ ./my_fpp_question.fpp produces course/questions/my_fpp_question/ and puts question files inside of that directory
• --make-dir is a flag whose presence says to explicitly create a directory with the question name (name of the source file) in the output path
  • default: true
  • metadata respective field: "make-dir" : bool
  • cli flags for negation: --no-make-dir, --no-duplicate-directories
  • e.g. questions/fpp_question/ $ generate_fpp.py --no-make-dir source_file.fpp produces a question inside of questions/fpp_question/ and NOT inside of questions/fpp_question/source_file/

Default behavior (create directory next to source path with source file name and write inside of it) is maintained.
