Ported VTK legacy readers to new reader architecture
Ported legacy readers to the new reader architecture such that they natively support file series. In the future, these readers will benefit from other improvements made to the overall architecture. Also developed the appropriate superclass for readers that are neither parallel nor time aware. In the process, I had to clean up a number of issues (classes subclassing from vtkDataReader unnecessarily for example).
