Tiling
•Data divided into “tiles” can be treated as one consolidated GPhys object.  Convenient to handle long time sequence divided by periods (such as by years) or outputs from parallel simulations on distributed-memory machines. Tiling is done by VArrayComposite.
•Subsets can be handled (see the figure below)
•May be applicable to parallel simulations in future?
•So far, automatic configuration is available only for NetCDF, by using an Array or Regexp (e.g., /data_x(\d)y(\d).nc/ for data_x0y0.nc, data_x0y1.nc, data_x1y0.nc, data_x1y1.nc)
