Detailed Description

A source link that stores just an index.

This is intentionally kept as barebones as possible. The source link is just a reference and will be copied, moved around, etc. often. Keeping it small and separate from the actual, potentially large, measurement data should result in better overall performance. Using an index instead of e.g. a pointer, means source link and measurement are decoupled and the measurement represenation can be easily changed without having to also change the source link.
