Add latex snippets/code completion in ACE editor

[shashaBot]

This task requires:
To create a snippets file in the root directory, latex.snippets which will be them imported in ACE editor instance.
For now, you can create the file with 1-2 snippets and then we can extend it later.

@shashaBot Could you please elaborate what we need to do in this issue?

[shashaBot]

Snippets are the piece of editor that powers things like autocomplete and bracket matching when the user presses [TAB]. We want to enable this for latex in ACE editor. ACE does not provide latex snippets on its own but fortunately, it has a mechanism through which we can create and register snippets for any language. That is precisely what we want to do.

Please see this file for example. The documentation for snippets is here.

Since creating an exhaustive snippets file would be difficult for any one individual we would like multiple collaborators on this issue.
