private: DISALLOW_COPY_AND_ASSIGN
Seems other function(s) are missing this too.

chrome/browser/extensions/extension_function_registry.h:22:14: error: no
matching constructor for initialization of 'WebviewExecuteScriptFunction'

Looks like ExtensionFunctionRegistry uses the default constructor. I'm leaving
it as is.

OK, I'd add a comment that says DISALLOW_COPY_AND_ASSIGN is intentionally left
out.

[Fady Samuel, 2013/06/25 19:22:05]

Looks like I was wrong. DISALLOW_COPY_AND_ASSIGN works, but I needed to add a
constructor. Done that.
