Large Files

I was looking at the HDF5 library and it turns out that there is metadata
available for the datasets. Therefore I think I'm going to do three things
after removing the config option:
1. Add new columns to the metadata view with the dataset information (size,
data type, dimensions)
2. Check the data size prior to projection and truncate it if it is too
big.
3. Update the documentation.
Does this sound like a good plan?
