 // This class centralizes all our code to get KioskMode settings; since
 // KioskMode interferes with normal operations all over Chrome, having all
 // data about it pulled from a central location would make future
 // refactorings easier. This class also handles getting trust for the policies
 // via it's init method.
 //
 // Note: If Initialize is not called before the various Getters, we'll return
 // invalid values.
 //
 // TODO(rkc): Once the enterprise policy side of this code is checked in, add
 // code to pull from the enterprise policy instead of flags and constants.

remove the TODO, as this is exactly what this CL is supposed to achieve AFAICS

[rkc, 2012/03/19 23:59:48]

Done.

nit: I hope it actually doesn't wait :)

Done.
