New atomic data for iron K emission and absorption as described
in Palmeri et al., 2004 A and A and references therein (see TK homepage
for reprints).
Added n=2-3 iron UTA absorption using data from FAC (Gu 2003).
Fixed bug which limited length of spectrum file name to 8 characters.
Fixed bug which allowed buffer containing ion fractions vs. xi to overflow when
the number of spatial zones exceeded 1000. Now the limit on the number of spatial zones is
3000, and the code stops with a message when this is exceeded.
Added accurate Voigt profile calculations for all lines in synthetic spectra.
Fixed bug which limited length of spectrum file name to 8 characters.
