##Description##
__nerv.Layer__ is the base class and most of its methods are abstract.
###Class hierarchy and their members###
-* __nerv.AffineLayer__ inherits __nerv.Layer__.
+* __nerv.Layer__.
+ * `table dim_in` It specifies the dimensions of the inputs.
+ * `table dim_out` It specifies the dimensions of the outputs.
+ * `string id` ID of this layer.
+ * `table gconf` Stores the `global_conf`.
+* __nerv.AffineLayer__ inherits __nerv.Layer__, both `#dim_in` and `#dim_out` are 1.
* `MatrixParam ltp` The liner transform parameter.
* `BiasParam bp` The bias parameter.
- * `table dim_in` should be of length 1.
- * `table dim_out` should be of length 1.

+* __nerv.BiasLayer__ inherits __nerv.Layer__, both `#dim_in` nad `#dim_out` are 1.
