docstr: Print out the summary information of an Analytics Zoo Keras Model.
  
  For each layer in the model, there will be a separate row containing four columns:
  ________________________________________________________________________________
  Layer (type)          Output Shape          Param #     Connected to
  ================================================================================
  
  In addition, total number of parameters of this model, separated into trainable and
  non-trainable counts, will be printed out after the table.
  
  # Arguments
  line_length The total length of one row. Default is 120.
  positions: The maximum absolute length proportion(%) of each field.
             List of Float of length 4.
             Usually you don't need to adjust this parameter.
             Default is [.33, .55, .67, 1.], meaning that
             the first field will occupy up to 33% of line_length,
             the second field will occupy up to (55-33)% of line_length,
             the third field will occupy up to (67-55)% of line_length,
             the fourth field will occupy the remaining line (100-67)%.
             If the field has a larger length, the remaining part will be trimmed.
             If the field has a smaller length, the remaining part will be white spaces.
