Fixed issue 2

I also set the default first year to be 1 more than the first sample
year
Merge pull request #16 from purpleplatypus/issue2

Fixed issue #2
No longer saves the year 0
Made my bit of code better, but skipping year 0 breaks everything
Trying to get the file importer to skip over year 0, but im not sure if this is the right way to fix the problem
Added some comments to help explain importing

But I'm really not sure how I'm going to fix this issue yet
Merge branch 'issue10' of https://github.com/purpleplatypus/FHAES into issue10
