Case insensitive for all metadata headers

[stheroux]

From a beta tester: "The ASCI calculator did not recognize 'UCS_mean', which is the output from Tyler's tool. I changed it to 'UCS_Mean' and it worked"

Would be great to allow for case insensitive metadata headers to be accepted (e.g. UCS_mean, UCS_MEAN, UCS_MeAN, etc).

Also, data exported from SMC data portal is in all lower case ... so would be good for any and all cases to be accepted

Im not quite clear on this one

Is UCS_Mean a GIS Metric?

[r7butler]

Yes it is a GIS Metric, got it

I think I will just have it expect lowercase column names from the station data, and convert all the station columns to lowercase when the thing runs

That would definitely work -- thanks!
