ENH: Set up the presets

[ZLLentz]

Description

Use the presets recently added to pcdsdevices. Create the presets/beamline and presets/proposalrunnum directories.

Motivation and Context

The people have spoken. We've split between the beamline presets that are permanent and the experiment presets that are not.

How Has This Been Tested?

Assume presets work in pcdsdevices, make sure we've set up the paths here.

Where Has This Been Documented?

In pcdsdevices

This will definitely fail on travis until we cut a new release for pcdsdevices with the presets.

[ZLLentz]

I'd like to have your opinions on:

• paths, are presets/beamline and presets/ls2516 good for the folders?
• function calls, currently the set is:

motor.presets.add_beamline
motor.presets.add_experiment
motor.presets.add_here_beamline
motor.presets.add_here_experiment

But I'm not sure if these should be shorter or changed, etc. of they are ok as is.

If you change this to pcdsdevices>v0.5.0 we can see it pass on the -dev build at least.

[teddyrendahl]

Tempted to change add_experiment to add_exp? Just a thought. Can't think of an appropriate shortening of beamline ... add_hutch. I don't know.

I'm fine with the YAML file paths.

[teddyrendahl]

This look good. Waiting for pcdsdevices release.

[ZLLentz]

Your shortenings seem appropriate. Let's sit on this just a bit longer, I want to get it in right before cutting the pcds-envs release.
