/**
|
|
* Makes an Error function with the signature:
|
|
*
|
|
* function(message, data)
|
|
*
|
|
* You'll typically do something like:
|
|
*
|
|
* var UnknownFileTypeError = makeError(
|
|
* 'UnknownFileTypeError',
|
|
* 'The specified type is not known.'
|
|
* )
|
|
* var er = UnknownFileTypeError()
|
|
*
|
|
* `er` will have a prototype chain that ensures:
|
|
*
|
|
* er instanceof Error
|
|
* er instanceof UnknownFileTypeError
|
|
*
|
|
* You can also do `var er = new UnknownFileTypeError()` if you really like the
|
|
* `new` keyword.
|
|
*
|
|
* @param String The name of the error.
|
|
* @param String The default message string.
|
|
* @param Object The default data object, merged with per instance data.
