Class OAuthFilter

Initalize Oauth filter wiht a tupple or list of tupples::

    (path, consumer, token, signaturemethod) 

token and method signature are optionnals. Consumer should be an 
instance of `oauth2.Consumer`, token an  instance of `oauth2.Toke` 
signature method an instance of `oauth2.SignatureMethod`.

With a list of tupple, the filter will try to match the path with 
the rule. It allows you to maintain different authorization per
path. A wildcard at the indicate to the filter to match all path
behind.

Example the rule::

    /some/resource/*
    
will match :

    /some/resource/other
    /some/resource/other2
    
while the rule `/some/resource` will only match the path 
`/some/resource`.
