Detailed Description
template<class TypeImpl>
class corelinux::Singleton< TypeImpl >
Ensure a class only has one instance, and provide a global point of access to it.
This is easier said than done outside of the solution domain. While we can declare a protocol by which the use of this type will prevent multiple applications, we can't insure that the implementor won't violate said protocol.
