Added from Developer:

• Longest Path Algorithm:

  • Introduced a new Longest Path Algorithm to calculate the longest paths in a graph.

• Tests for Longest Path Algorithm:

  • Implemented tests to verify the correctness and reliability of the Longest Path Algorithm.

• Mapping Functions for FGraph and AdjGraph:

  • Included mapping functions for both FGraph (Functional Graph) and AdjGraph (Adjacency Graph) to facilitate transformations and manipulations on graph structures.

• Filter Functions for FGraph and AdjGraph:

  • Added filter functions for both FGraph and AdjGraph, allowing users to selectively include or exclude elements based on specific criteria.

• Minor Fix for Documentation
