Measurement Applicator

[jro1234]

Something that is basicallyt a surrogate for analysis "task". Just get the basic functionality to:
(use the xyztraj repo for now to implement as a custom feature)

• read trajectory data
• apply feature function to trajectory data
• determine "score" for frames and select top-score guy

This one requires major addition to design.

• deliver this info to walkers somehow at runtime.
