"VAO" is written in Iris output files (minor)

[jbudynk]

Some output files have "VAO" written in them. E.g., output from saving a SED in ASCII format, saving integrated fluxes (same method as used for saving ASCII SEDs). Here's example output from saving an ASCII SED:

# This file was generated by Iris, the VAO SED building and analysis tool
#
# File created on Mon Mar 02 11:23:07 EST 2015
#
#
# TARGET = NGC 7714

This is most likely trivial to fix, but since we had more pressing issues to deal with, I am putting it back to backlog.
