Feature Request: Option to omit headings? Or to omit a regex?

[JocelynTuohy]

Would it be possible to add an option to omit headings from the word cloud? I imagine that, if you wanted this to be less corner-case, this could be broadened to omit content based on one or more regexes. Thanks for considering!

I would like to tell it where my Templates folder is at and to not count words there, my current word clouds are dominated by the default headers and prompts i use in my notes.
