* Provides bundling of:

*
*
* An {@link DynamicLibraryBundleInfo} instance is being passed in the constructor,
* providing the required information about the tool and glue libraries.
* The ClassLoader of it's implementation is also being used to help locating the native libraries.
*
* An instance provides a complete {@link com.jogamp.common.os.DynamicLookupHelper}
* to {@link com.jogamp.gluegen.runtime.ProcAddressTable#reset(com.jogamp.common.os.DynamicLookupHelper) reset}
* the {@link com.jogamp.gluegen.runtime.ProcAddressTable}.
* At construction, it:
*
* - loads the Tool native library via
* {@link com.jogamp.common.os.NativeLibrary#open(java.lang.String, java.lang.ClassLoader, boolean) NativeLibrary's open method}
* - loads the {@link com.jogamp.common.jvm.JNILibLoaderBase#loadLibrary(java.lang.String, java.lang.String[], boolean, ClassLoader) Glue native library}
* - resolves the Tool's {@link com.jogamp.common.os.DynamicLibraryBundleInfo#getToolGetProcAddressFuncNameList() GetProcAddress}. (optional)
