-/**
- * EvaluatorLongDescription
- *
- * Long descriptions for evaluators are created and stored in an Excel spreadsheet
- * where they are formatted for readability with things like bold subheadings.
- * That formatting is mostly lost -- with the exception of line breaks --
- * when the spreadsheet is converted into a CSV for inport into the tool's database.
- *
- * Eventually the spreadsheet's contents may be maintained in a location
- * where they can be styled with a WYSIWYG editor. For now, this component provides
- * a workaround by taking a long description string that is only formatted with
- * line breaks and restoring some of the formatting from the spreadsheet by:
- *     - splitting the string into segments at double line breaks
- *     - splitting the segements into lines at single line breaks
- *     - formatting the first line of a segment as an H4 if it does not contain a
- *       pseudo code symbol
- *     - formatting all other lines as paragraphs
- *
