"""
This script has several functions and operators... grouped for convenience
* assign material:
offers the user a list of ALL the materials in the blend file and an
additional "new" entry the chosen material will be assigned to all the
selected objects in object mode.
in edit mode the selected polygons get the selected material applied.
if the user chose "new" the new material can be renamed using the
"last operator" section of the toolbox.
After assigning the material "clean material slots" and
"material to texface" are auto run to keep things tidy
(see description bellow)
* select by material
in object mode this offers the user a menu of all materials in the blend
file any objects using the selected material will become selected, any
objects without the material will be removed from selection.
in edit mode: the menu offers only the materials attached to the current
object. It will select the polygons that use the material and deselect those
that do not.
* clean material slots
for all selected objects any empty material slots or material slots with
materials that are not used by the mesh polygons will be removed.
* Any un-used materials and slots will be removed
