Issue MDL-43855: Implement a new equation editor for Atto
We have several sources to choose from. The requirements of the equation editor seem to be: 1/ Work with existing equations created with dragmath etc. 2/ Provide tabs with buttons for adding common latex elements (See mathquill) 3/ Provide live equation preview while editing the equation 4/ Show preview of equation in text editor (even before content is saved) 5/ Allow access to the tex source of the equation 6/ Allow editing of an existing equation without downloading/uploading files. This is tied to the choice for filter for rendering equations, because the filter should be responsible for displaying the equations in the live preview, and/or the content editable region. There is an equation editor in the prototype.moodle.net site which uses mathjax, but it does not give you a list of tabs/buttons for common functions (not a useful one anyway).
