		The trees block is structured as follows:
			* the root element takes the same attributes as 
			  characters elements do: an id, a reference
			  to a taxa element, and various optional
			  attributes.
			* the trees element contains one or more tree/network
			  elements, which are the same structure as
			  GraphML documents (http://graphml.graphdrawing.org/),
			  with the following extentions:
			  	- there are two subclasses (xsi:type="nex:Tree" and
			  	  xsi:type="nex:Network"), which only differ in the
			  	  constrained in-degree of node elements (one for 
			  	  trees, one or more for networks)
			  	- node elements can have an additional taxon attribute
			  	  to refer to a taxon element defined earlier 
			  	- edge elements can have a 'length' attribute
			  	  to specify edge length/weight, which is a 
			  	  IEEE 754-1985 compliant floating point number on 
			  	  trees of type FloatTree.
