Initial Pytorch API

Release 0.4.0

Major Features And Improvements

• Added initial Pytorch API with PytorchReceptiveField.

Multiple feature maps

Release 0.3.0

Major Features And Improvements

• Update Keras and Tensorflow api for multiple feature maps calculation
• Change of api in compute function: removed output_layer: str
  and replaced with output_layers: List[str], which can accept a list
  of names for feature maps for which we want to compute receptive fields.
• Change in plot_gradient_at, added new parameter which control for
  which feature map gradient is plotted. Same for plot_rf_grid function.
• New functions for plotting: plot_rf_grids and plot_gradients_at.
• Improved tensorflow API, now one does have to initialize model with
  InteractiveSession, this is handled by the TFReceptiveField.
• A new API for tensorflow: TFFeatureMapsReceptiveField.
