Print the vocabulary (number of tokens) of functions and files.

The option --function displays the file name, function name,
line number of the function, the number of tokens

The default option --summary displays the file name, the average vocabulary
of all functions in the file and a score ranging from 0 to 100.

Usage:
$ longbow-vocabulary-report parc_JSON.c
parc_JSON.c  51.00 100.00

$ echo parc_JSON.c | longbow-vocabulary-report --function -o csv -
