  "Description": "Provides the basic functionality to interact with the\nCollatz conjecture. The parameterisation uses the same (P,a,b)\nnotation as Conway's generalisations. Besides the function and\nreverse function, there is also functionality to retrieve the\nhailstone sequence, the \"stopping time\"/\"total stopping time\",\nor tree-graph. The only restriction placed on parameters is\nthat both P and a can't be 0. For further reading, see\n<https://en.wikipedia.org/wiki/Collatz_conjecture>.",
