@BHoMBot this is a DevOps instruction. I am requesting neutral checks on: versioning, code-compliance, unit-tests, ready-to-merge

[bhombot-ci]

@FraserGreenroyd I have provided neutral checks to the checks requested. These checks will need to be run properly to obtain full results.

Versioning failures are not related to this PR. Check dispensated for time being.
