convert PDB file to Ansys key points and lines

To use these scripts:
1. create a protein data bank file of your structure
2. name it test.pdb and save it in a folder: C:\xyz
3. make sure you have python installed
4. and to make things easier for development and use, grab the free version of Wingware IDE 101
