Improve filtering of reports by directory, particularly for use with monorepos about code-compass

[ag91]

Hi @ambirdsall-gogo , I am really happy you are using code-compass: I made this mode to help users like you!
The idea of the directory exclusion is good, I would welcome a PR.
One question: are the projects in your monorepo Git repository themselves?
If so, you will like the feature I plan to release this week. It lets you do run a hotspot analysis on a directory containing multiple repositories. You can also specify the repositories to pick in a text file, which may do with your filtering needs.

Great, I will put that first PR together soon when I have some free time.

One question: are the projects in your monorepo Git repository themselves?

There is a single git repository for the entire group of projects, each of which is, from git's perspective, just another subdirectory within a single project. I would be surprised if the new feature will work for my use case without any modification, but it has significant overlap with what I'm hoping to do, and I look forward to seeing what I can learn from it. If nothing else, it will be an example of how the API should be designed for the filtering I seek.

Meanwhile, I have to do some more reading of the source code to clarify my understanding of the report-generation process, starting with the input data for the d3 visualizations. If the generated cloc report is what defines the set of circles to be drawn, with the git analyses being queried to determine each circle's fill, then that may be the correct entry point for filtering a git directory to a subset of its source files; but since I am speculating about things I can learn for myself, I will stop there for now.
