General cleanup questions

Inconsistent use of data and configs directories

There are inconsistencies in the existence/use of data/ and configs/ directories in each directory in RAIL/src/rail.

	configs in ./	configs in ./configs/	data in ./	data in ./data/
RAIL/src/rail/examples/creation	x	yes	x	yes
RAIL/src/rail/examples/estimation	x	x	yes	yes
RAIL/src/rail/examples/goldenspike	yes	x	x	yes

We aso have some stray configs outside of src/rail, such as RAIL/examples/core/pipe_example_config.yml.

• Do we have a preference for always using directories, or always avoiding their use?
• Do we want to strictly keep all config files within src/rail?

Pipelines directory

Currently, is has its own .gitignore containing just *.*~, and nothing else in RAIL seems to use it.

• Is this meant to just be a landing spot for users who also install rail_pipelines?
• Do we want to encourage users who install rail and build their own pipelines to place them in that directory?

Attic

There's an attic directory at RAIL/examples/goldenspike/attic/.

It seems to create at least a nonzero amount of maintainability work; I've noticed Drew had to update a couple of the utils in his PR deprecating Brier and PIT.

The name attic implies a place for old/unused things, but this seems like a directory that lets the user interact with goldenspike outside of a notebook.

• Are we keeping it around for users who want more than just a notebook? If so, do we want to rename the directory to something more descriptive?
• Otherwise, do we want to just delete it?

Misc

• I'm currently working on #182, so skipping over outdated READMEs/html renders
• RAIL/examples/evaluation/utils.py -> do we want a utils file in our examples directory? If so, can we rename this to reflect that?
