We're introducing a new "list of accessions", similar to current implementation of AccessionList.

Model

Add a new entity Subset to ..model.impl:

public class Subset extends AuditedVersionedModel implements AclAware {

  @Type(type = "uuid-binary")
  protected UUID uuid;

  protected boolean published;

  // other strings, only description is @Lob
  // dateCreated as string -- it's not the same as createdDate (from Auditing)
  protected String title, description, publisher, rights, dateCreated, publisher;

  @ManyToMany(cascade = {}, fetch = FetchType.LAZY)
  @JoinTable(name = "SubsetAccessions", joinColumns = @JoinColumn(name = "subsetId"), inverseJoinColumns = @JoinColumn(name = "acceId"))
  private List<AccessionId> accessionIds;
}

1. Add JPA repository
2. Implement service

Controller and JSP

Add a new SubsetController at /subset with the following methods

1. GET /subset/ listSubsets() that renders the list of Subsets where published == true.
2. GET /subset/{uuid} subset() that renders all properties of the Subset + the passport data of accessions in the subset. It should use the components from browse.

REST API controller

New controller at /api/v1/subset with endpoints:

1. POST /list Page<Subset> list(@RequestBody SubsetFilters filter)
2. GET /{uuid} Subset get(@PathVariable UUID uuid)
3. POST /create Subset create(@RequestBody Subset subset)
4. POST /update Subset update(@RequestBody Subset subset)
5. DELETE /{uuid},{version} Subset delete(@PathVariable UUID uuid, @PathVariable int version)
