img_dim variable is used to store the product of the dimensions of an image. For example, for a 2x2 image, img _dim = 4.
However, the above initialization of the class TTN (and, also MERA) doesn't explain what img_dim is or how it is used in the entire code. Perhaps, instead, this variable should be renamed to qubits or something better.
