      Description

      I like to see the coalesce-function from SQL implemented in ObjectUtils. Something like this:
      <T> T ObjectUtils.coalesce(T... t)
      The first object, which is not null will be returned. This would replace all the defaultValue/defaultString/... methods, with al flexibler and shorter method. It will also reuse an existing name.

      I think it's simple. Perhaps there should be overloading methods with fixed parameter sizes. Following the jdk this seems to a little faster:
      <T> T ObjectUtils.coalesce(T t1, T t2)
      <T> T ObjectUtils.coalesce(T t1, T t2, T t3)
      ...

      I would provide it, including tests, if you like.
