v1.2.0

Additions:

• Now you can remove single instances:

var immstruct = require('immstruct');
var structure = immstruct('key');

immstruct.remove(structure.key);

• Immstruct now exposes the internal instance object:

var immstruct = require('immstruct');
var structure = immstruct('key');

immstruct.internals[structure.key] //=> Structure

With this you can iterate over the instances and do more fancy things - use it with care.
