// Unfortunately the deserialization is a two-step process:
// 1. First we decode a stream into some intermediate representation
// (called "GSerialized");
// 2. Then we produce an ade::Graph from this intermediate representation.
//
// An ade::Graph can't be produced from the stream immediately
// since every GCompiled object has its own unique ade::Graph, so
// we can't do it once and for all since every compilation process
// is individual and _is_ altering the ade::Graph state (structure and metadata).
// At the same time, we can't hold the reference to "is" within the GComputation
// forever since this input stream may be associated with an external resource
// and have side effects.
//
// Summarizing, the `deserialize()` happens *once per GComputation* immediately
// during the cv::gapi::deserialize<GComputation>(), and `reconstruct()` happens
// on every compilation process issued for this GComputation.
