public class LayoutWriterStack
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>

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
