Re #6807. Add log warning on unfulfilled request for historical data.

If an event-based live listener does not support historical data, then
tell the user that they're only going to be getting data from the
algorithm launch time onwards.
Re #6807. Use non-stream logger for fixed string.

Also set the start time to zero rather than the current time, for
consistency with what's done above. The end result will be the same.
Re #6807. Make comments more general.

The previous comments don't belong in this general class as they were
talking about very specific SNS/ADARA/SMS things.
Removed title from categories. Refs #9521.
Added local table of content to algorithm. Refs #9521.
Use figure rather than image. Refs #9521.

- This allows a caption to be added that contains the algorithms name, to make the screenshot's purpose clearer.

refs #9509. Skeleton algorithm.
Hard code section header names rather than using the module titles

It's clearer where the section names come from and avoids any unwanted
module qualifications when the directives become part of a package.
Refs #9521
Add supporting code to generate screenshot in algorithm directive

Refs #9521
Add gitignore & README for images directory.
