Start implementing get_related_holons query

[evomimic]

NOTE: THIS ISSUE HAS CHANGED SINCE ITS ORIGINAL DEFINITION

The original title of this issue was _Implement get_relatedholons query and implementation was begun in branch 84. However, as the implementation scope, grew a different path to implementation seemed preferable.

Proposal

• Define finer-grained issues that the _get_relatedholons dance depends on.
• Define a new issue that will complete the implementation of this query dance AFTER dependencies have been satisfied.
• After confirming the implementation work that had already begun does not break anything (all sweetest cases still pass), merge branch 84 into main

Tasks

• [x] Rename this issue to "_Start implementing get_relatedholons query"
• [x] Define finer-grained issues that the _get_relatedholons dance depends on.
  • [x] Issue #105
  • [x] Issue #106
• [x] Define a new issue that will complete the implementation of this query dance AFTER dependencies have been satisfied (DONE: See Issue #107)
• [ ] After confirming the implementation work that had already begun does not break anything (all sweetest cases still pass), file a PR to merge this branch into main
• [ ] Delete branch 84
• [ ] Close issue 84

Following closure of this issue:

• Begin implementing (and merging into main) the dependent issues first
• Create the branch for Issue #107 only AFTER all dependencies have been met.

this branch is up to date with main, therefore closing.
