Declare a new Gaudi property.

Parameters

Inform a dynamic data consumer about all consumed or produced data.

Parameters

input_data_in	the input data object IDs of all algorithms and tools
output_data_in	the output data object IDs of all algorithms and tools
new_input_handles	the new input data handles added by this call
new_output_handles	the new output data handles added by this call
