Pull Request Overview
This pull request enhances the max flow analysis capability in the ngraph library by introducing detailed analytics via the FlowSummary, additional helper functions for sensitivity analysis and bottleneck identification, and updated documentation and examples.
- Enhanced calc_max_flow to optionally return elaborate flow analytics and the flow graph.
- Added new helper functions (saturated_edges, run_sensitivity) for sensitivity and bottleneck analysis.
- Updated test coverage and documentation examples to demonstrate the new analysis capabilities.

- [nitpick] Consider renaming the fixture 'line1' to a more descriptive name (e.g., 'simple_graph') to improve readability and clarity in the tests.

This pull request introduces enhancements to the
calc_max_flowfunction. These changes enable sensitivity analysis and bottleneck edge identification.Enhancements to
calc_max_flowand related utilities:return_summaryandreturn_graphflags tocalc_max_flow, enabling the function to return aFlowSummaryobject with detailed analytics and/or the mutated flow graph. The return type now supports multiple formats based on these flags.saturated_edgesto identify bottleneck edges andrun_sensitivityto perform sensitivity analysis on edge capacities. These utilities provide deeper insights into capacity bottlenecks.FlowSummarydata structure: Introduced an immutableFlowSummaryclass to encapsulate edge flows, residual capacities, reachable nodes, and min-cut edges.Updates to documentation and examples:
