Student couldn't able to submit his answer in ie9
becuase mathjax was used before its complete loading
thats cuase the problem. Mathjax operations should be
handled synchronously inorder to avoid error.

Declare variables locally
- The `allSections` variable was leaking into the global scope, due to a
typo in the declaration.
- `dataProcessed` can be declared more narrowly within the callback.
to successfully call a function with parameters by setTimeout,
it needs to be a function that will be called by setTimeout internally.
this patch actually enables multiple tries for calling the setState function.
Change the `MathJax.Hub.Queue(initializeRequest)` to a simpler function call
(`initializeRequest.call(this)`). This was failing to give a proper context
to initializeRequest, and `this.value` was turning up as `undefined`.
Also add a fallback if we need to display some code before MathJax finishes
its original typesetting.
I was stubbing out `Queue` in my specs, so the tests had to be changed around
a little.
Named `FormulaEquationInput` (name up for debate)
- Based off ChemEqnIn
- Add FormulaEquationInput in inputtypes.py
- Add a call to a skeleton method for a preview
javascript:
- Queue up some MathJax
- Put some ordering on the AJAX requests: add a parameter when the request was started, when it returns check that it isn't outdated before displaying the preview
- Tests
Note: we moved the `jsinput` tests and DISABLED them, because they were causing the tests to fail.
