Matrix and other default expressions in new Atto equation editor

      MOODLE_27_STABLE

      Description

      With Atto text editor and equation editor enabled (using MathJax filter)

      Select the Equation editor Advanced tab, The matrix (last) button does not display properly and inserts:

      \left| \begin

      {matrix} a_1 & a_2 \ a_3 & a_4 \end{matrix}

      \right|

      rather than:

      \left| \begin

      {matrix} a_1 & a_2 \ \ a_3 & a_4 \end{matrix}

      \right|

      Needs to be fixed in the settings,php file where the \ \ denoting the matrix new line needs to be \\\\. Presumably an escaping issue.

      Also, consider adding a few more useful default expressions.
