There isn't a way to access the materials library.  However, you can get 
the same effect by defining a file that contains just the materials that 
you want and loading it at the beginning of your Lua script to get 
definitions of the materials that you need.

Yes, although in FEMM 3.3 and lower, this is sort of a kludge.  Check 
the documentation of the runpost command in the manual--it shows how to 
pass a small amount of information via the call to run the 
postprocessor.  Otherwise, you can use a temporary file to pass 
variables (i.e. write them in the preprocessor, read them in the 
postprocessor).  The Lua scrips on the examples page at 
http://femm.foster-miller.com/examples.htm use the temporary file method.

In v4, there is only one instance of Lua that controls both the pre- and 
post-processor at the same time, eliminating the problem of passing 
information from the preprocessor tothe postprocessor.
