Make \DeclareMathOperator and \Newextarrow localizable by begingroup. #1876 (!1908) · Merge requests · MathJax / MathJax

Merged Davide P. Cervone requested to merge github/fork/dpvc/issue1876 into develop Jan 20, 2018

Move setDef() and setEnv() to TeX jax, and use them for \DeclareMathOperator and \Newextarrow so they can be localized via the begingroup extension. Also, no need to wait for newcommand any longer, since setDef() and setEnv() are predefined now.
