NodeValidatorBuilder class

Class which helps construct standard node validation policies.

By default this will not accept anything, but the 'allow*' functions can be used to expand what types of elements or attributes are allowed.

All allow functions are additive- elements will be accepted if they are accepted by any specific rule.

It is important to remember that sanitization is not just intended to prevent cross-site scripting attacks, but also to prevent information from being displayed in unexpected ways. For example something displaying basic formatted text may not expect <video> tags to appear. In this case an empty NodeValidatorBuilder with just allowTextElements might be appropriate.
