* KaTeX mhchem.js
*
* This file implements a KaTeX version of mhchem version 3.3.0.
* It is adapted from MathJax/extensions/TeX/mhchem.js
* It differs from the MathJax version as follows:
* 1. The interface is changed so that it can be called from KaTeX, not MathJax.
* 2. \rlap and \llap are replaced with \mathrlap and \mathllap.
* 3. Four lines of code are edited in order to use \raisebox instead of \raise.
* 4. The reaction arrow code is simplified. All reaction arrows are rendered
* using KaTeX extensible arrows instead of building non-extensible arrows.
* 5. \tripledash vertical alignment is slightly adjusted.
*
* This code, as other KaTeX code, is released under the MIT license.
*
* /*************************************************************

/*************************************************************
*
* KaTeX mhchem.js
*
* This file implements a KaTeX version of mhchem version 3.3.0.
* It is adapted from MathJax/extensions/TeX/mhchem.js
* It differs from the MathJax version as follows:
* 1. The interface is changed so that it can be called from KaTeX, not MathJax.
* 2. \rlap and \llap are replaced with \mathrlap and \mathllap.
* 3. Four lines of code are edited in order to use \raisebox instead of \raise.
* 4. The reaction arrow code is simplified. All reaction arrows are rendered
* using KaTeX extensible arrows instead of building non-extensible arrows.
* 5. \tripledash vertical alignment is slightly adjusted.
*
* This code, as other KaTeX code, is released under the MIT license.
*
* /*************************************************************
*
* MathJax/extensions/TeX/mhchem.js
*
* Implements the \ce command for handling chemical formulas
* from the mhchem LaTeX package.
