constants with prefix and postfix options

# Constance

Create constants with ease. Inspired by React's `keyMirror` module, Constance accepts an object and mirrors the keys onto their values. Constance also allows you to prefix and postfix constants, either to provide proper namespacing or cut down on the verbosity of writing out constants. Constance works with arrays too.

```sh
npm install constance
```

```js
var constance = require('constance');

var methods = ['save', 'update', 'validate'];

// normal
var events = constance(methods);
/* => {
  save: 'save',
  update: 'update',
  validate: 'validate'
} */

// prefixing
var hooks = constance('pre_', methods); 
/* => {
	save: 'pre_save',
	update: 'pre_update',
	validate: 'pre_validate'	
} */

// postfixing
var actions = constance(methods, '_action');
/* => {
	save: 'save_action',
	update: 'update_action',
	validate: 'validate_action'	
} */
```
