Title: Add Math Expression to markdown editor in Studio.

Provides possibility to add a Math Expression input from the common problem type editor ([BLD-486](https://edx-wiki.atlassian.net/browse/BLD-486)).
Screenshots are in the ticket.

For example:
```
= \(a + b\)
```
should result in
```xml

```
It should default to each variable having the range [-10,10] with ten samples, a tolerance of .000001 and input size of 40, as shown. If the user us unsatisfied with these default values, she can change them using the advanced editor.

@sarina, @singingwolfboy, @frrrances please review.
