Detailed Description

template<class TypeImpl> template class corelinux::Singleton

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.
