SoSFTrigger — field used to trigger engines or connection networks

       This  class can be used to start or to synchronize a network of field connections. It is the "null" field
       — a field with no values. It is typically used as the "start button" for engines that change over time.

       Triggers can be connected from any other type of field, and will notify any engines  or  nodes  they  are
       part  of (or any other triggers they are connected to) whenever the value of the field is set (even if it
       is set to its current value) or the field is touch()'ed.

       Since they have no value, SoSFTriggers  are  not  written  to  file.  A  node  or  engine  containing  an
       SoSFTrigger field will write only the field's name.

voidsetValue()
          Starts the notification process; this is equivalent to calling touch().

     voidgetValue()
          Forces any connected engines or fields to evaluate themselves.

     intoperator==(constSoSFTrigger&t)constintoperator!=(constSoSFTrigger&t)const
          All trigger fields are equal; these methods always return TRUE and FALSE, respectively.
