Rewritten SharedHandle. Now copy constructor taking raw pointer has keyword explicit and SharedHandle's default constructor initializes its internal obj to null, old implementation initializes it using obj's default constructor. To assign null, write SharedHandle<T> x(...); x.reset(); TODO: test/SharedHandleTest.cc needs more tests. * src/SharedHandle.h
