API thoughts for zookeeper mkdir -p

proposal.js

// 
// How would you prefer to use a mkdir-p API?
// Note that this is for making directories in ZooKeeper :)
// 


// 
// Option #1
// 
var mkdirp = require('zk-mkdirp');

var connection = new ZooKeeper(/* ... */);

mkdirp(connection, path, callback);


// 
// Option #2
// more complicated to program, and possibly bad b/c require is sync, and 
// users might want to create the connection to zookeeper after the first tick
// of the event loop.
// 
var connection = new ZooKeeper(/* ... */);
var mkdirp = require('zk-mkdirp')(connection);

mkdirp(path, callback);


// 
// Option #3
// best of both worlds? just plain awkward if you only use it once?
//
var mkdirp = require('zk-mkdirp');

var connection = new ZooKeeper(/* ... */);

mkdirp.connection = connection;
mkdirp(path, callback);
