// Import reads the file using the FileIO interface and returns it's content.

// The flags parameter is a bitwise combination of pre-defined PostFlags which
// determine if and how post processing of the data should occur.
//
// The properties map defines various importer properties to utilize.
//
// If successfull the data is returned in the Scene structure which should be
// considered read-only (as the assimp library owns the memory), and a nil
// error is returned.
//
// If failure occurs a nil *Scene and a human-readable error is returned.
