Details:

When reading the metadata of FITS tables, to fill the blank value, we need to
know the column data type before hand. 

However, Samane Raji recently pointed me to a FITS table downloaded from the
SDSS database where TNULL (the key for the blank element) came before TFORM
(the key for the column datatype). This caused a crash in Table, not allowing
us to see the table contents. 

I am now busy adding a step to avoid this problem (and interpret such 'TNULL's
after reading all other the header keywords).
