Version 1.0

1. Added in a software version check. The user is presented with a dialog letting them know if there is a more recent version of the software available on the server.

2. Cells containing NaN (-999) are now ignored. Previously the values of -999 were included in the output and the user was given a warning that they existed. Now data values of -999 are not included in the output, and the user is not given a warning about their existance.

3. Blank data cells are now ignored. Previously a user was not allowed to select a blank data cell.

   Processing is still aborted if a selected cell has either a blank site code or variable acronym (ie blank data cells are allowed, blank row and column headings are not allowed).

Version 0.0 beta

1. Program operates as documented in software user manual
