/**
* @brief Convolve the input with a bank of learned filters, and (optionally)
* add biases, treating filters and convolution parameters in the
* opposite sense as ConvolutionLayer.
*
* ConvolutionLayer computes each output value by dotting an input window with
* a filter; DeconvolutionLayer multiplies each input value by a filter
* elementwise, and sums over the resulting output windows. In other words,
* DeconvolutionLayer is ConvolutionLayer with the forward and backward passes
* reversed. DeconvolutionLayer reuses ConvolutionParameter for its
* parameters, but they take the opposite sense as in ConvolutionLayer (so
* padding is removed from the output rather than added to the input, and
* stride results in upsampling rather than downsampling).
