 Markdown-it 12.0.4 source 
 markdown-it/blob/master/lib/rules_inline/strikethrough.js adapted to fit MarkBind's needs, to:
 - create new inline rules dynamically for different delimiters 
 */
 
/**
 * Creates a new inline rule for markdown-it, specifically for rules that uses a 'double' delimiter.
 * Some examples are ++, --, !!, %%. 
 * @param delimiter Represents the double delimiter to be used to create tokens when parsing.
 * @param ruleName The name that represents the rule you are creating.
 * @param nextRule There is a precedence ordering for the rules in markdown-it. This parameter
 * lets you decide which rule to place your newly created rule before. You may refer to the following 
 * link for the existing inline rules in markdown-it.
 * https://github.com/markdown-it/markdown-it/blob/master/lib/parser_inline.js
