## Latent
### A writable stream that buffers data until you decide where to write it.

** Alpha, use at your own risk **

Latent is a writable stream that buffers data until you know where you need to write it.  When you do, call open(filename).  If you decide not to write the file, call close().

#### Installation

  npm install latent
  
#### Example

    var latentStream = new latent.Latent();
    
    //obviously you'd actually use this for uploads or other network streams
    process.stdin.pipe(latentStream);
    
    determineWhereToSave(function onDetermineComplete(whereToSave)
    {
      if(err)
        return(latentStream.close());
      
      //ensure the directory exists
      mkdirp(path.dirname(whereToSave), function onMkdirpComplete(err)
      {
       if(err)
          return(latentStream.close());
       
       latentStream.open(whereToSave);
      });
    });
