"""
This plugin computes the standard representation for all objectives
and constraints. All results are stored in a ComponentMap named
"_repn" at the block level.
We break out preprocessing of the objectives and constraints
in order to avoid redundant and unnecessary work, specifically
in contexts where a model is iteratively solved and modified.
we don't have finer-grained resolution, but we could easily
pass in a Constraint and an Objective if warranted.
Required:
model: A concrete model instance.
