/** \class DynamicLoader
* \brief Portable loading of dynamic libraries or dll's.
*
* DynamicLoader provides a portable interface to loading dynamic
* libraries or dll's into a process.
*
* Directory currently works with Windows, Apple, HP-UX and Unix (POSIX)
* operating systems
*
* \warning dlopen on *nix system works the following way:
* If filename contains a slash ("/"), then it is interpreted as a (relative
* or absolute) pathname. Otherwise, the dynamic linker searches for the
* library as follows : see ld.so(8) for further details):
* Whereas this distinction does not exist on Win32. Therefore ideally you
* should be doing full path to garantee to have a consistent way of dealing
* with dynamic loading of shared library.
*
* \warning the Cygwin implementation do not use the Win32 HMODULE. Put extra
* condition so that we can include the correct declaration (POSIX)
