validate called in initialize, not consistent with docs

[pmackay]

The README suggests to construct a Validator and then call validator.validate. This is not necessary as validate is called in initialize. This results in double the number of recorded issues.

Suggest either fix the docs or remove call to validate in initialize?

This bit me too.

yes it would be nice to update the docs. I had to look at the code to figure this out. thanks!
