implement trials form

[wholmgren]

Some ideas from discussion this morning:

• Add /trials page that looks like /reports but only shows the reports that were generated by the trials the user participated in. Add "Request trial" in place of "create new report".
• "Request trial" form contains elements like:
  • requesting username, organization prepopulated by logged in account
  • title
  • observations section. specify previously created observations (could be simple links/uuids for now). no ability to request new sites/obs through this section.
  • forecasts section. specify previously created forecasts for each observation OR specify forecast metadata in form that will apply to all observations
  • metrics section.
  • categories section.
  • data qualification toolkit section.
  • date ranges for training data and for evaluation period.
  • forecast providers section. Box to list specific forecast providers (email addresses or organization names) that we should invite to participate. Checkbox to request that we invite all organizations that have signed up for the to be created "open trial invitation list". The list is public (maybe a viewable google spreadsheet).
  • Submit button. Sends an email to admin@solarforecastarbiter.org, we manually process and communicate with the requester.
• We create a document for sharing the specifications with the requested forecasters. (medium term:) Document is a web page that shows up on /trials... (long term:) with status like invited, accepted, declined and document is superseded by trial report once it gets underway.
• Maybe /reports has a filter to exclude reports that are generated by the trial process.

Should consider a relatively free-form form in addition to a very prescriptive form.

Certainly would be useful to have a formal page describing trial parameters (the equivalent of our test trial blog posts but on the dashboard and hooked up to a database).
