Class that can be used by "layout" tags, i.e. tags that use the different parts in their body to assemble a bigger part. Example a threeColumn tag that expects a left, center and right part in its body and places them in a table:
  <g.threeColumn>
      <g.left>left contents</g.left>
      <g.center>middle contents</g.center>
      <g.right>right contents</g.right>
  </g.threeColumn>

Returns a java.io.Writer where a layout part can write its contents to. This method should only be called by tags that are part of a surrounding layout tag. Example:
  def left = { attrs, body ->
      LayoutWriterStack.currentWriter('left') << "<div class='left'>" << body() <<"</div>"
  }
  
  
     name -  Name of the layout partExecutes the body closure of a tag and returns a Map with namned results that hold the content of the parts within the body. This method should only be called by tags that are part of a surrounding layout tag. Example:
  def parts = LayoutWriterStack.writeParts(body)
  out << "left part:" << parts.left << "; right part:" << parts.right << ";remainder of body:" << parts.body
  
  
     body -  the body closure of the calling "layout" tag
