### Removing extra vertices in OpenStudio

In a classic case where a surface that can be completely defined by x vertices is actually defined with x+1 vertices, EnergyPlus throws a warning and drops the extra vertex:

   ** Warning ** GetVertices: Distance between two vertices < .01, possibly coincident. for Surface=7A4912D16DF6446A9238, in Zone=1-LEFT-CORRIDOR
**   ~~~   ** Vertex [2]=(45.27,140.25,0.00)
**   ~~~   ** Vertex [1]=(45.28,140.25,0.00)
**   ~~~   ** Dropping Vertex [2].


These warnings clutter my error file and distract me from the real stuff.

So, is there any script out there to just strip them out of the OSM file?
