+ * \brief Feature Map Shape
+ *
+ * This class describes the shape of feature maps, which serves as the input/output of 2D
+ * convolutional operations (e.g. Convolution).
+ *
+ * Each feature map is a collection of 3D features conceptually.
+ * Each feature has depth, height, width.
+ *
+ * count() refers to the number of features in a feature map
+ * depth() refers to the depth of features in a given feature map
+ * height() refers to the height of features in a given feature map
+ * width() refers to the width of features in a given feature map
