New creates a new instance of the Calculator.

WithLogger returns option to specify logging component.

Calculator is a processor of a single iteration of EigenTrust algorithm.

Prm groups the required parameters of the Calculator's constructor.

AlphaProvider must provide information about required alpha parameter for eigen trust algorithm.

InitialTrustSource must provide initial(non-calculated) trusts to current node's daughter.

IntermediateWriter must write intermediate result to contract.

IntermediateWriterProvider must provide ready-to-work IntermediateWriter.

PeerTrustsIterator must iterate over all nodes(PeerIDs) and provide TrustIterator for iteration over node's Trusts to others peers.

TrustIterator must iterate over all retrieved(or calculated) trusts and call passed TrustHandler on them.

Option sets an optional parameter of Controller.
