case class TreeLookup(tree: Value[SAvlTree.type], key: Value[SByteArray], proof: Value[SByteArray]) extends Quadruple[SAvlTree.type, SByteArray, SByteArray, SOption[SByteArray]] with Product with Serializable
Perform a lookup of key key in a tree with root tree using proof proof.
Throws exception if proof is incorrect
Return Some(bytes) of leaf with key key if it exists
Return None if leaf with provided key does not exist.

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.
