DeepCopy is a recursive object cloning library designed to create independent copies of complex nested objects. It functions as a state snapshot utility and object cloning tool that produces clones while preserving the original object graph.
The library includes a circular reference handler to duplicate data structures containing self-referencing loops without causing infinite recursion. It also serves as an object property transformer, allowing for the filtering or modification of specific fields and types during the cloning process based on custom matching criteria.
