A custom detector construction pattern for Geant4 applications

Geant4 Detector Construction Pattern (G4DCP) is a template developed to flexibly construct complex detectors in Geant4 applications. The elements of G4DCP, including G4VUserDetectorConstruction, form an elegant template for detector setups. We construct a sample detector geometry utilizing this template and make the developed code available to the public.Geant4探测器构建模式（Geant4 Detector Construction Pattern，G4DCP）是为在Geant4应用中灵活构建复杂探测器而开发的模板。该模式的组成元素（包含G4VUserDetectorConstruction）构成了一套优雅的探测器搭建模板。我们基于该模板构建了一款示例探测器几何结构，并将开发的代码向公众开放。
