Generate a proper log per-project

[cartermp]

Generate a log in markdown for users. Default path is the bin directory, like BenchmarkDotNet.

The log should include information about detecting things that aren't directly convertable. Examples:

• App.config files
• TODO

Converting TODO items is easy. Just leave them as TODO ;-)

That's my signal to my future self to say, "Hey, you should really think about this"

It'll probably mean using ILogger tho
