RegExp support for custom tag

[tianranwangcs]

Say there is a set of custom tags like !customTag1, !customTag2, !customTag3 ... in the yaml file. We don't know the number of such tags before loading it. Is there a way to use RegExp /!customTag[\d]*/ when creating schemas?

This parser does not use regexp, but your demand can be done via #385 when complete.

Added in 73ef02c (currently in dev branch).

See an example how to do it here:
https://github.com/nodeca/js-yaml/blob/a0d0caa5aa0f5354fefa9c637cfb7c4c17ef7d02/examples/handle_unknown_types.js

Note that it works using prefix, not RegExp.
