IAF to IAGA conversion does not allow for writing G #79

Charles Blais:

Data contained in the IAF are xyzg. However, when writing to IAGA2002, it tries to write xyzf. I used the keyword "useg" as stated in the code and I am still getting XYZF on the ouput.

There was an error within the IAGA export code, if G values were present but no F, as it happens when reading IAF. I corrected this one. As long as G values are available, IAGA will always contain them. If only F values are available, you can provide the useg option to automatically calculate G. Otherwise F values are written to the file.
