Option to count tokens instead of lines or characters

[eyalroz]

After reading #234, it immediately occurred to me it that parsed tokens are a more valid measure of code size than characters. After all,

my_value = perform_some_actions();

is the same thing as

v = do_stuff();

I realize this is a tall order and perhaps out-of-scope for this project, but - I'll just put it out there.

Theoretically it's a fine idea. However cloc does not parse languages; it is strictly regular-expression based. For this reason, character counting is possible (although unlikely to be implemented in the foreseeable future), but counting tokens is not. You'll need a smarter counter than cloc!
