Check for memory leaks and circular memory references

Perl’s garbage collection has one big problem Circular references can’t get cleaned up. The above example is the sort of thing that sometimes trips me up, where a code reference inside a data structure refers to another part of the data structure. There already exists a good testing module to find these sort of problems TestMemoryCycle, so why write this one? Well that module uses TestBuilder, and this one instead uses Test2API. If you want to write Test2Suite tests without pulling in TestBuilder then this is the cycle testing module for you.

Test2ToolsMemoryCycle also uses the standard Exporter interface, instead of letting you specify a test plan. That behavior was once in vogue I guess, but I do not care for it.
