v0.31 Update

1) Now the script will change the selection to vertices from edge or polygon if needed. 

2) New option, (which is now the default), to do a distance weighted average. Previously it would only do a simple average, (my original description had said it was a weight average but that was a error). This was okay as long as on the connected vertices were about the same distance away. With the weighted average vertices further away will have less of an influence. Thus the morph value will be more accurate.
