Insert LaTeX formatting

Zulip's compose box has a smart Math (LaTeX) () button, which inserts contextually appropriate LaTeX formatting:

If no text is selected, the button inserts displayed LaTeX (````math`) formatting.
If selected text is on one line, the button inserts inline LaTeX ($$) formatting.
If selected text is on multiple lines, the button inserts displayed LaTeX (````math`) formatting.

(optional) Select the text you want to format.
Click the Math (LaTeX) () icon at the bottom of the compose box to insert LaTeX formatting.

You can also use the **Math (LaTeX)** (<i class="zulip-icon zulip-icon-math"></i>)
icon to remove existing LaTeX formatting from the selected text.

To use displayed LaTeX, use triple backticks and the word math (````math`) followed by some text and triple backticks at the end:

``` math
\int_a^b f(t)\, dt = F(b) - F(a)
```
