  ------------------------------------------------------------------------------------------------------------------------------------
  A library for importing JSON feeds into Google spreadsheets. Functions include:
     ImportJSON            For use by end users to import a JSON feed from a URL
     ImportJSONAdvanced    For use by script developers to easily extend the functionality of this library
  Future enhancements may include:
   - Support for a real XPath like syntax similar to ImportXML for the query parameter
   - Support for OAuth authenticated APIs
  Or feel free to write these and add on to the library yourself!
  ------------------------------------------------------------------------------------------------------------------------------------
  Changelog:
  
  1.1    Added support for the noHeaders option
  1.0    Initial release
 *====================================================================================================================================*/
/**
 * Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create
 * a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in
 * the JSON feed. The remaining rows contain the data.
 *
 * By default, data gets transformed so it looks more like a normal data import. Specifically:
 *
 *   - Data from parent JSON elements gets inherited to their child elements, so rows representing child elements contain the values
 *      of the rows representing their parent elements.
 *   - Values longer than 256 characters get truncated.
 *   - Headers have slashes converted to spaces, common prefixes removed and the resulting text converted to title case.
 *
 * To change this behavior, pass in one of these values in the options parameter:
 *
 *    noInherit:     Don't inherit values from parent elements
 *    noTruncate:    Don't truncate values
 *    rawHeaders:    Don't prettify headers
 *    noHeaders:     Don't include headers, only the data
 *    debugLocation: Prepend each value with the row & column it belongs in
 *
 * For example:
 *
 *   =ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json", "/feed/entry/title,/feed/entry/content",
 *               "noInherit,noTruncate,rawHeaders")
 *
 * @param {url} the URL to a public JSON feed
 * @param {query} a comma-separated lists of paths to import. Any path starting with one of these paths gets imported.
 * @param {options} a comma-separated list of options that alter processing of the data
 *
 * @return a two-dimensional array containing the data, with the first row containing headers
 * @customfunction

/**
 * An advanced version of ImportJSON designed to be easily extended by a script. This version cannot be called from within a
 * spreadsheet.
 *
 * Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create
 * a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in
 * the JSON feed. The remaining rows contain the data.
 *
 * Use the include and transformation functions to determine what to include in the import and how to transform the data after it is
 * imported.
 *
 * For example:
 *
 *   =ImportJSON("http://gdata.youtube.com/feeds/api/standardfeeds/most_popular?v=2&alt=json",
 *               "/feed/entry",
 *                function (query, path) { return path.indexOf(query) == 0; },
 *                function (data, row, column) { data[row][column] = data[row][column].toString().substr(0, 100); } )
 *
 * In this example, the import function checks to see if the path to the data being imported starts with the query. The transform
 * function takes the data and truncates it. For more robust versions of these functions, see the internal code of this library.
 *
 * @param {url}           the URL to a public JSON feed
 * @param {query}         the query passed to the include function
 * @param {options}       a comma-separated list of options that may alter processing of the data
 * @param {includeFunc}   a function with the signature func(query, path, options) that returns true if the data element at the given path
 *                        should be included or false otherwise.
 * @param {transformFunc} a function with the signature func(data, row, column, options) where data is a 2-dimensional array of the data
 *                        and row & column are the current row and column being processed. Any return value is ignored. Note that row 0
 *                        contains the headers for the data, so test for row==0 to process headers only.
 *
 * @return a two-dimensional array containing the data, with the first row containing headers
