/**
* @class vtkSMInputProperty
* @brief proxy representing inputs to a filter
*
* vtkSMInputProperty is a concrete sub-class of vtkSMProperty representing
* inputs to a filter (through vtkSMProxy). It is a special property that
* always calls AddInput on a vtkSMSourceProxy.
* The xml configuration for input proxy supports the following attributes:
* multiple_input: For an input port that connects multiple connections
* such as the input of an append filter. port_index: The input port to
* be used.
