比较两个java对象语义平等（也包括deephashcode）

Official source code kept here: https://github.com/jdereg/java-util Use the reference below to include DeepEquals and a few other powerful utilities in your project. com.cedarsoftware java-util 1.8.0 Use DeepEquals.deepEquals(a, b) to compare two Java objects for semantic equality. This will compare the objects using any custom equals() methods they may have (if they have an equals() method implemented other than Object.equals()). If not, this method will then proceed to compare the objects field by field, recursively. As each field is encountered, it will attempt to use the derived equals() if it exists, otherwise it will continue to recurse further. This method will work on a cyclic Object graph like this: A->B->C->A. It has cycl
