Select Similar Objects

First, I think both groups (Include & Exclude) are clear additional options
About "Compare By..." group:

• Class (it's self explained)
• Material (it's also self explained). You can use this on all objects.
  For exampe: you can select quickly all nodes w/o material applied
  Or: select all nodes with the same instance material applied.
  Note(!): It's possible to have a unique materials with the same names so
  I compare the material instances for correct "similar" handler.
• Size (it's clear too) - to enjoy good performance in Max 9 end below
  just install AVG extensions (it needs for this op's only).
  I add an alternative method to can use the script w/o AVG, of course.
  The choice is yours.
• Mesh - First, am not compare edges 'cause they're faces multiplied by 3.
  This op's compare Not only Geometry but Shapes as well.
  Shapes are compared by their renderable mesh (not by knots/segs/spl.)
  This op's check Meshes so I found this method for correct handler.
