新建一个线程，让某个类在新线程中执行的方法

/*myMoveToThread

 * usage：

 * class A：public QObject

 * A *a;//exec in current thread

 * class OtherClass:public QObject

 * OtherClass *otherClass;//exec in new thread

 * connect(a,&A::someSignal,otherClass,&OtherClass::someSlot);

 * connect(otherClass,&OtherClass::someSignal,a,&A::someSlot);

 * //Critical(Next Line)!!! otherClass MUST HAVE A PATH TO DESTROY

 * connect(a,&A::destroyed,otherClass,&OtherClass::deleteLater);

 * myMoveToThread(otherClass);

 *

 * Then class named otherClass is running at a new Thread.

 * While otherClass destroyed(),then the new thread will be deleted.

 * Otherwise,the new thread never quit,even though application exit.
