named-queue

like async.queue, but tasks are named and de-duplicated

Init

`var namedQueue = require('named-queue')`

`var queue = new namedQueue(processor, concurrency)`

`processor` - `function(task, cb)`

`concurrency` - `Number` for maximum concurrent tasks; can be `Infinity`

Methods

WARNING All tasks must have an .id property used to identify and avoid doing the same task more than once at a time

`queue.push(task, cb)`

`queue.unshift(task, cb)`

`queue.length()`
