Data extractor

Extracts data from given database connectors.

Each connector needs at least the following exported methods:

function connect(cb) {
    //connect to database, return callback with (null,true) if successful
    cb(null, true)
}

function insert(object, cb){
    //...
    //insert object into db
    cb(null, success);
}

function getLastBlock(cb){
    //check db for highest block number inserted
    //return blocknumber or -1 if nothing is inserted yet.
}

function disconnect(){
    //close db connection
}
