Unsupported browsers   老版本不支持，ie7带特殊meta
    Firefox 1.0: no means (beside cookies and flash)
    Safari 2: no means (beside cookies and flash)
    Safari 3: no synchronous api (has asynch sqlite api, but store.js is synch)
    Opera 9: don't know if there is synchronous api for storing data locally
    Firefox 1.5: don't know if there is synchronous api for storing data locally
    Microsoft IIS & IE7: With meta tag & "charset=iso-8859-1", things stop working. See issue #47.

Storage limits
    IE6 & IE7: 1MB total, but 128kb per "path" or "document" (see http://msdn.microsoft.com/en-us/library/ms531424(v=vs.85).aspx)
    See http://dev-test.nemikor.com/web-storage/support-test/ for a list of limits per browser
    
    
例子
    
// Store 'marcus' at 'username'
store.set('username', 'marcus')

// Get 'username'
store.get('username')

// Remove 'username'
store.remove('username')

// Clear all keys
store.clear()

// Store an object literal - store.js uses JSON.stringify under the hood
store.set('user', { name: 'marcus', likes: 'javascript' })

// Get the stored object - store.js uses JSON.parse under the hood
var user = store.get('user')
alert(user.name + ' likes ' + user.likes)

// Get all stored values
store.getAll().user.name == 'marcus'

// Loop over all stored values
store.forEach(function(key, val) {
    console.log(key, '==', val)
})
