Convert Latex mathematical notations to PGML for use in WebWork: Clipboard Fusion Macro

latex_to_pgml.cs

// This Clipboard Fusion macro makes it easy to copy Latex from the Learning Standards Project into WebWork compatible formats

// The 'text' parameter will contain the text from the:
//   - Current Clipboard when run by HotKey
//   - History Item when run from the History Menu
// The returned string will be:
//   - Placed directly on the Clipboard when run as a Macro
//   - Ignored by ClipboardFusion if it is 'null'
//   - Passed along to the next action in a Trigger (null changed to an empty string)
