Tiered Map

































A simple map of key value pairs with support for tiers (e.g. defaults go at tier 25, standards go at 50, and overrides go at tier 75)

## Usage

```javascript

var TieredMap = require('tiered-map')

var m = new TieredMap({

	tiers: {

		'high': 75

	}

	onChangeListener: function(key, newValue, oldValue){

		console.log('The key', key, 'changed from', oldValue, 'to', newValue)

	}

})

m.set('name', 'ben')  // name defaults to ben (default level is 50)

m.set('name', 'bob', 25)  // name will stay bob

m.set('name', null)  // name will become bob

m.set('name', 'john', 'high')  // name will become john

console.log(m.get('name', 75))  // will output john

console.log(m.get('name'))  // will output nothing

console.log(m.get('name', 25))  // will output bob

console.log(m.getTier('high'))  // will output 75

```

Very useful for having multiple tiers of data attributes with different priorities. For example, you could have default values at tier 25, adjusted values at tier 50, and override values at tier 75.
