Problem/motivation

Provide an option, per bundle, to create templates based on a per entity flag.
Use case: share with RePEc a subset of entities from an entity type bundle, and not all of them.

Proposed resolution

Optionally set, on the bundle configuration, a boolean field to restrict the share per entity.
While content access could be an option for this case, some entities can still be public and not be shared on RePEc, so a flag is a more flexible option.

The author field set from the bundle configuration could be from several types (user reference, text, ...). The current implementation assumes that the user reference type is the default.

Currently, the module has a limitation to the plain Author-Name attribute for the paper template.
Which opens the possibility for plain text field as source type.
However, user reference makes sense, because the paper template allows to set multiple attributes:

• Author-Name-First
• Author-Name-Last
• Author-Email
• Author-Workplace-Name

See https://ideas.repec.org/t/papertemplate.html

A minimal implementation needs at least a field validation during the field mapping on the bundle settings form, then coverage for other types if necessary.

The author field can be multiple, as described in the paper template
https://ideas.repec.org/t/papertemplate.html
Currently, only the first field value is set.

The Drupal 7 module handled the first author only.
The way the template is written needs to be adjusted to allow several authors: currently, the Author-Name is an indexed key from an array so it does not allow multiple values.
