Added line to remove 0 values from minimum criteria evaluation.
Added line to only include A, A+ and B data.
Fixed conversion from ng to ug and added mg to ug covnersion.
Changed source for criteria evaluation from data.wo.void to data.wo.newmethods but I think we want it to actually be data.wo.void. More thought on this required.
.gitignore is in this commit but I don't know why.
Not sure why this keeps showing up as modified
In the criteira.R file I made sure to pull out the criteria that show 0 as an artifact from excel in the applicable criteria data frame.

In the toxics analysis I switched back the data frame for the criteria evaluation to the data wo void so we could see the new methods included.

Not sure what changed with the data summary draft excel file. Learning that changes in xlsx files don't show up in the R studio diff.
