#async-memo
Call a function at most once and remember the result. Args are not supported.
##Example
var memo = require('async-memo')
var doc = memo(function(cb) {
// fetch remote document
// you want this to be done only once
fetch(cb)
})
doc(function(err, val) {
// use fetched document here
})
// You can safely call doc() from everywhere at any time.
// fetch() will be called only once.
