Sherpa Prototype

- started evaluation function for program
- made jquery-ui.js sortable divs
- added tabs - probably going to remove them unless I style them
- added numbered lined in order to be ready to update model based on drag'n'drop sorting
- evaluation of program works now

Previous version was before the myprogram.js is fully integrated
- integrating myprogram.js
- separate rendering of header / body / tests
- group under rdr global variable all of the tags used in these functions
- use tables to render both headers & tests
