Protocols should pass settings between each other

[DStrelak]

Is your feature request related to a problem? Please describe.
Every time I add a protocol, I have to remember metadata such as sampling rate and symmetry of the input. Since Protocols have mostly single input, this seems unnecessary.

Describe the solution you'd like
Protocols should automatically pass metadata about their input/output to the successive protocols. I should be, however, able to manually edit them, should it be necessary.

@DStrelak could you give an example? I'm not following " Protocols have mostly single input"

[DStrelak]

@azazellochg I didn't select proper wording.
What I meant to say is that the protocols have typically a single protocol's output as an input (e.g. movie alignment has an import movies as an input) , or, in case of 'combining' protocols (e.g. classification, which takes particles and reference volume), input with same properties (e.g. resolution).

David, all the information that is attached to a given input object, we don't ask the user input it again in the protocol. If you find a protocol where this is not happening, please open a specific issue for the case.
