//  This file defines the `CFGMatchSwitch` abstraction for building a "switch"
//  statement for control flow graph elements. Each case of the switch is
//  defined by an ASTMatcher which is applied on the AST node contained in the
//  input `CFGElement`.
//
//  Currently, the `CFGMatchSwitch` only handles `CFGElement`s of
//  `Kind::Statement` and `Kind::Initializer`.
