    @short          "baseclass" to make own classes threadsafe
    @descr          Sometimes you must share your lock- or mutex member with any other baseclasses.
                    And baseclasses are initialized erlier then members! That's why you should use
                    this struct as first of your baseclasses!!!
                    Then you will get a public member "m_aLock" which can be used by special guard implementations
                    to make your code threadsafe.

    @seealso        class LockHelper

    @implements     -
    @base           -

    @devstatus      ready to use
