prototype monotonicity analysis for hydroflow

A rough prototype for Hydroflow consistency analysis, in the spirit of Bloom's budplot tool.

Input should be a .dot file, as produced by the Hydroflow method serde_graph().to_dot(). The output is a file taint.dot that is a recoloring of the input graph. The legend should be as follows:

Edges:

• Solid vs Dotted edges: deterministic vs non-deterministic ordering
• Green vs Red edges: monotone vs non-monotone sources

Nodes:

• Solid vs Dotted border: deterministic vs non-deterministic ordering
• Green border: monotone
• Blue/Yellow/Gray fill: consistent (untainted). These colors come from Hydroflow (Blue is pull, yellow is push, gray is handoff).
• Red fill: Inconsistent (tainted), i.e. downstream of non-determinism AND non-monotocity -- hence inconsistent (across runs or replicas)

Example:

% python3 flowrules.py graph-joins.dot
% dot -Tpdf taint.dot > taint.pdf
% open taint.pdf

I also recomment the VScode extension for Graphviz to save the trouble of running dot and generating pdfs.
