--[=[-------------------------< C O I N S _ R E P L A C E _ M A T H _ S T R I P M A R K E R >------------------ There are three options for math markup rendering that depend on the editor's math preference settings. These settings are at [[Special:Preferences#mw-prefsection-rendering]] and are PNG images TeX source MathML with SVG or PNG fallback
All three are heavy with html and css which doesn't belong in the metadata.
Without this function, the metadata saved in the raw wikitext contained the rendering determined by the settingsof the last editor to save the page.
This function gets the rendered form of an equation according to the editor's preference before the page is saved. Itthen searches the rendering for the text equivalent of the rendered equation and replaces the rendering with that sothat the page is saved without extraneous html/css markup and with a reasonably readable text form of the equation.
When a replacement is made, this function returns true and the value with replacement; otherwise false and the intitalvalue. To replace multipe equations it is necesary to call this function from within a loop.
