Commit Message

Allow automatic discovery of header from a BigFile.

This improves the usability of reading a saved catalog.
A saved catalog saves the attrs in Header column, but when we
read it in from BigFileCatalog the default was not to use
that column, creating confusions.

Original email report of the issue:
```
I’m having some difficulty saving and reading files using CatalogSource. I have a simple script like below to save the ArrayCatalog data:

    # create the catalogue
    particle_data = {}
    particle_data['Position'] = pos
    particle_data['Velocity'] = vel
    particle_data['ID'] = Id
    cat = NBlab.ArrayCatalog(particle_data, BoxSize=header['boxsize'])
    cat.save(dir+’/Matter', ["Position", "Velocity"])

This saves everything nicely into the Matter directory. But Later when I try to read in this data using something like
cat = BigFileCatalog(‘Matter’)
I get the following: “Error: Dataset length is inconsistent on Position“

Is there something I need to specify in the save command in order for me to properly read the data in using BigFileCatalog?
```
