[RUBY] QUESTION: Is Avro::SchemaValidator class accessible in version 1.8.2?

I can't seem to access `Avro::SchemaValidator.validate!()` in the current version 1.8.2. I was wondering if this class is being made public in a future version or am I missing something in how I use it? It seems that it is not one of the accessible classes from the Avro module, if this is the case, I was wondering what the reason for this would be?

I figured doing 
```
require 'avro'
Avro::SchemaValidator.validate!(schema, data)
```
Would be enough. 

I was interested in the ValidtionError class to return specific error messages.

Thank you!
