Summary
The ODynmaicLoader provides a special load on call mechanism for dynamic libraries which support a C-API.
Description
The libraries must provide a struct with function pointers for all supported C functions. The loader loads the specified library and call the specified initialization function to initialize the function pointers with the real functions. Furthermore provides the loader a reference counter for the library. When the last instance of the laoder will be destroyed the loader will unload the library. Do not use.

ODynamicLoader< API > &
operator=( const ODynamicLoader< API > & toAssign ) throw( );
