This PR causes nested delimiters to be handled properly (not closing the delimiters until the inner ones are also closed). It also fixes the spacing issue around the delimiters (the physics package prevents the stretchy delimiters from getting TeX class INNER, so I've removed the properties that cause
setTeXclass()to mark it as INNER so that it will be handled as a normalmrowwith an OPEN at the front and a CLOSE at the end). Also, some operators were being enclosed inmirather thanmo, producing the wrong spacing (e.g., in\divand\curl), so I've changed that as well to match the LaTeX output. Finally, an expression that is missing its final delimiter would produce a math input error, so I've added the missing error message so that the missing close delimiter will be reported.This resolves issues mathjax/MathJax#2760 and mathjax/MathJax#2831.
