/**

 * Find target entities related to a source entity

 * Returns all target entities that have a particular relationship to the

source entity. Note, relationships are one way.

For example, the following method finds all content that the current user

has an 'ignore' relationship with:

`GET /wiki/rest/api/relation/ignore/from/user/current/to/content`

Note, 'ignore' is an example custom relationship type.

**[Permissions](https://confluence.atlassian.com/x/_AozKw) required**:

Permission to view both the target entity and source entity.
