refactor main BDF reading

[GoogleCodeExporter]

the FEM_Mesh.py file is a reasonable name if bdf.py didnt exist. bdf.py 
performs mainly card field writing and a better name is probably 
fieldWriter.py. This would then allow FEM_Mesh.py to be replaced with bdf.py 
(rename it).

Futhermore, FEM_Mesh_helper.py is a bad name, and should be split into multiple 
files. Maybe (with the existing approach (FEM_Mesh_addMethods, 
FEM_Mesh_cardBuilder, etc.). This could also be changed to bdf_addMethods, etc.)

Summary:
bdf.py -> fieldWriter.py
FEM_Mesh.py -> bdf.py
FEM_Mesh_helper.py -> bdf_helper.py
bdf_helper.py -> bdf_addMethods.py, bdf_deleteMethods.py, bdf_writeMethods.py, 
cardObject.py

-----------------------------
done:
bdf.py -> fieldWriter.py
FEM_Mesh_helper.py -> bdf_helper.py
bdf_helper.py -> BDF_Card.py

more to come!

FEM_Mesh.py now has:
 - Subcase class
 - CaseControlDeck class

pull them out...

done:
FEM_Mesh.py -> subcase.py & caseControlDeck.py
FEM_Mesh.py renamed to bdf.py
FEM_Mesh class renamed to BDF

bdf_helper.py -> bdf_addMethods.py & bdf_writeMesh.py 

consider making BDF_Card a member of BaseCard.  also consider renaming BDF_Card 
to be more consistent
