* The IDBStore constructor
*
* @constructor
* @name IDBStore
* @version 1.1.0
*
* @param {Object} [kwArgs] An options object used to configure the store and
* set callbacks
* @param {String} [kwArgs.storeName='Store'] The name of the store
* @param {String} [kwArgs.storePrefix='IDBWrapper-'] A prefix that is
* internally used to construct the name of the database, which will be
* kwArgs.storePrefix + kwArgs.storeName
* @param {Number} [kwArgs.dbVersion=1] The version of the store
* @param {String} [kwArgs.keyPath='id'] The key path to use
* @param {Boolean} [kwArgs.autoIncrement=true] If set to true, IDBStore will
* automatically make sure a unique keyPath value is present on each object
* that is stored.
* @param {Function} [kwArgs.onStoreReady] A callback to be called when the
* store is ready to be used.
* @param {Function} [kwArgs.onError=throw] A callback to be called when an
* error occurred during instantiation of the store.
* @param {Array} [kwArgs.indexes=[]] An array of indexData objects
* defining the indexes to use with the store. For every index to be used
* one indexData object needs to be passed in the array.
* An indexData object is defined as follows:
* @param {Object} [kwArgs.indexes.indexData] An object defining the index to
* use
* @param {String} kwArgs.indexes.indexData.name The name of the index
* @param {String} [kwArgs.indexes.indexData.keyPath] The key path of the index
* @param {Boolean} [kwArgs.indexes.indexData.unique] Whether the index is unique
* @param {Boolean} [kwArgs.indexes.indexData.multiEntry] Whether the index is multi entry
* @param {Function} [onStoreReady] A callback to be called when the store
* is ready to be used.
* @example
// create a store for customers with an additional index over the
// `lastname` property.
var myCustomerStore = new IDBStore({
dbVersion: 1,
