PIC freq counter notes

I am capturing some notes for how to use a PIC MCU as a frequency counter. I would like to potentially include this in some other projects that I am looking at. There are some interesting ideas and the counter does not look too complex. I wonder if a person could prototype it to the point where it is a reproducible "component" that could be easily included in other designs.

It seems like there is a lot of potential for reuse for a tool/module like this. I
will try to look into this more tonight after the kids go to bed. There is no end
to amount of reading that I can come up with.
