   Now, users can define a new layer like this. (Just three functions)
   ```
   class MyLayer(layer.Layer):
       def __init__(self, a, b, c):
           super(MyLayer, self).__init__()
           self.l1 = layer.Linear(a,b)
           self.l2 = layer.Linear(b,c)
           # just need to specify names of params and states
           self.param_names = ['W', 'b']
           self.state_names = self.param_names + ['running_mean', 'running_var']
   
       def initialize(self, x):  
           ## init params, no need to enable the graph manually, the graph will be enabled automatically
           pass
   
       def forward(self, x):
           y = self.l1(x)
           y = self.l2(y)
           ### other statements
           return y
   ```
