Matches a constructor initializer if it is initializing a base, as opposed to a member.
+
+Given
+  struct B {};
+  struct D : B {
+    int I;
+    D(int i) : I(i) {}
+  };

+    E() : B() {}
+  };
+constructorDecl(hasAnyConstructorInitializer(isBaseInitializer()))
+  will match E(), but not match D(int).
+
+ + Matcher<CXXCtorInitializer>isWritten 
Matches a constructor initializer if it is explicitly written in
 code (as opposed to implicitly added by the compiler).
