When BuildInternal returns null, an parsing error has occured. braContents and kerContents should be checked for null and return null.

Additional tests regarding parsing errors inside \bra and \ket should be added to TestErrors at the bottom of this file. The current implementation doesn't handle these cases correctly.

Ok, I replicated some of the parsing error tests for powers and \sqrt.

- Changed \bra and \ket to \Bra and \Ket - Added a comment linking back to the original LaTeX package - Added parse error unit tests for \Bra and \Ket

I've made all of the requested changes. Let me know if there's anything else you need. |

Resolution/Implemented
This pull request adds the
\bra{}and\ket{}commands, which are useful shorthand commands for work involving quantum mechanics and Dirac notation.Example of a common use case:
Their implementation is inspired by the popular braket LaTeX package.
