Asynchronously lists both files and subdirectories in a directory.

Example

var FileSystem = require("FuseJS/FileSystem");

FileSystem.listEntries(FileSystem.dataDirectory)
    .then(function(entries) {
        console.log("There are " + entries.length + " entries in directory")
    }, function(error) {
        console.log("Unable to list entries in directory due to error " + error);
    });
