Modifies Contents API to return Error objects...

Modifies Contents API to return Error objects Modfies the Contents class to return JavaScript Error objects instead of passing on the return values from $.ajax(). This has two advantages. First, it allows the content manager to parse errors and give more informative messages than the ajax response. Second, it makes the Contents interface more general, since other kinds of backends might generate client-side errors.

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      includes the func_code attribute of any function.  Once unpickled, new

      functions can be built using new.function(code, globals()).  Eventually

      we need to automate all of this so that functions themselves can be pickled.
