[gradsusr] Station data

[Jayakrishnan P.R]

I think the problem is with the exact reading of the text file and writing
as binary file due to formatting. Could you send me the unformatted text
file may be like this. I have done this without formatting as your case.
*2016 02 17 22 station1 60.749 -0.854 1005 *
*2016 02 17 22 station2 60.139 -1.183 1006 *
*2016 02 17 22 **station3 60.447 -1.277 950  *
