 From what i understand the code was written so that editmesh is a 
temporary structure for manipulating Mesh datablocks. The two major 
functions for manipulating mesh data  are make_editMesh() and  
load_editMesh().  make_editMesh() takes the Global editobject and then 
creates all the edit data structs for you based on the mesh data. You 
can manipulate these structures and then call load_editMesh() to 
recreate the mesh based on the editdata and then the editdata is 
released.  Clearly ppl are going to need to enter editmode on meshs that 
are already created to be able to manipulate their data.  How do people 
do this?
