The type of the value represented by this node.
The type of the value represented by this node. If the value is an operation it is the type of operation result.
Unique id of the node class used in serialization of ErgoTree.

Every value represents an operation and that operation can be associated with a function type, describing functional meaning of the operation, kind of operation signature.
Every value represents an operation and that operation can be associated with a function type, describing functional meaning of the operation, kind of operation signature. Thus we can obtain global operation identifiers by combining Value.opName with Value.opType, so that if (v1.opName == v2.opName) && (v1.opType == v2.opType) then v1 and v2 are functionally point-wise equivalent. This in particular means that if two _different_ ops have the same opType they _should_ have different opNames. Thus defined op ids are used in a Cost Model - a table of all existing primitives coupled with performance parameters.
