   * Common processors are:
   *
   *   sending              - sending code to Espruino (no data)
   *   transformForEspruino - transform code ready to be sent to Espruino
   *   transformModuleForEspruino({code,name})
   *           - transform module code before it's sent to Espruino with Modules.addCached (we only do this if we don't think it's been minified before)
   *   connected            - connected to Espruino (no data)
   *   disconnected         - disconnected from Espruino (no data)
   *   environmentVar       - Board's process.env loaded (object to be saved into Espruino.Env.environmentData)
   *   boardJSONLoaded      - Board's JSON was loaded into environmentVar
   *   getModule            - Called with data={moduleName:"foo", moduleCode:undefined} - moduleCode should be filled in if the module can be found
   *   getURL               - Called with data={url:"http://....", data:undefined) - data should be filled in if the URL is handled (See Espruino.Core.Utils.getURL to use this)
   *   terminalClear        - terminal has been cleared
   *   terminalPrompt       - we've received a '>' character (eg, `>` or `debug>`). The argument is the current line's contents.
   *   terminalNewLine      - When we get a new line on the terminal, this gets called with the last line's contents
   *   debugMode            - called with true or false when debug mode is entered or left
   *   editorHover          - called with { node : htmlNode, showTooltip : function(htmlNode) } when something is hovered over
   *   notification         - called with { mdg, type:"success","error"/"warning"/"info" }

// directly start an expression (like a quotation mark) or can

  To use this, on your plugin's `init` function, do something like the
  following:

  Espruino.Core.Config.add("MAX_FOOBARS", {
    section : "Communications",           // Heading this will come under in the config screen
    name : "Foobars",                     // Nice name

    defaultValue : 20,
    onChange : function(newValue) { ... }
  });

    * onChange will be called whenever the value changes from the default
      (including when it is loaded)

  Then use:

 * Escope (<a href="http://github.com/estools/escope">escope</a>) is an <a

 * scope analyzer extracted from the <a
 * href="http://github.com/estools/esmangle">esmangle project</a/>.
 * <p>
 * <em>escope</em> finds lexical scopes in a source program, i.e. areas of that

 * variable. With each scope the contained variables are collected, and each
 * identifier reference in code is linked to its corresponding variable (if
 * possible).
 * <p>
 * <em>escope</em> works on a syntax tree of the parsed source code which has
 * to adhere to the <a

 * Mozilla Parser API</a>. E.g. <a href="http://esprima.org">esprima</a> is a parser
