DFCloudCloudDistance component

Computes the distance between 2 point clouds

Inputs:

i_cloud_source (pointcloud ,list)	The source point cloud.
i_cloud_target (pointcloud ,list)	The target cloud.
i_swap (bool ,item)	whether to swap source and target

Outputs:

o_distances	list of calculated distances for each point of the source.
o_rmse	root mean squared error between source and target.
o_max_deviation	max deviation between source and target
o_min_deviation	min deviation between source and target
o_std_deviation	standard deviation between source and target.
o_result	The result of the distance calculation.
