*
* This class is a sequential id generator. A simple use of this class would be like so:
*
* Ext.define('MyApp.data.MyModel', {
* extend: 'Ext.data.Model',
* idgen: 'sequential'
* });
* // assign id's of 1, 2, 3, etc.
*
* An example of a configured generator would be:
*
* Ext.define('MyApp.data.MyModel', {
* extend: 'Ext.data.Model',
* idgen: {
* type: 'sequential',
* prefix: 'ID_',
* seed: 1000
* }
* });
* // assign id's of ID_1000, ID_1001, ID_1002, etc.
*
