/*!
  Make a duplicate of this node and return a pointer to the duplicate.

  If this node is a group node, children are also copied and we return
  a pointer to the root of a full copy of the subgraph rooted here.

  If \a copyconnections is \c TRUE, we also copy the connections to
  fields within this node (and ditto for any children and children's
  children etc).


  Note that this function has been made virtual in Coin, which is not
  the case in the original Open Inventor API. We may change this
  method back into being non-virtual again for major Coin versions
  after this, as it was made virtual more or less by mistake. So
  please don't write application code that depends on SoNode::copy()
  being virtual.

  The reason this method should not be virtual is because this is \e
  not the function the application programmer should override in
  extension nodes if she needs some special behavior during a copy
  operation (like copying the value of internal data not exposed as
  fields).

  For that purpose, override the copyContents() method. Your
  overridden copyContents() method should then \e both copy internal
  data aswell as calling the parent superclass' copyContents() method
  for automatically handling of fields and other common data.
