/* A macro to disable the copy constructor and assignment operator.

|
When building with C++11 and above, the methods are explicitly
|

|
|
|
deleted, causing a compile-time error if something tries to copy.
|
|
|
|
|
For C++03, this just declares the methods, causing a link-time
|
|
|
|
|
error if the methods end up called (assuming you don't
|
|
|
|
|
define them). For C++03, for best results, place the macro
|
|
|
|
|
under the private: access specifier, like this,
|
|
|
|
|
|
|
|
|
|
class name_lookup
