Clang and Grappalang schema storing

Adding scheme storing for clang and grappalang
Add script to run clangrunner and grapparunner 
Rename runclang to run_query
Removing unused viz operators

- [ ] address comments
- [ ] tests
Is there a way to add a line of code to the file later? I want to add writeTuplesUnordered  to the end of the timing code, right now it is being added to the end of store, but still needs the params.
