1. Modified fitting function to take the minimum and maximum of the doses tested across all plates (rather than within a plate) as the value for extremely reactive or non-reactive cases

2. Added a customized outlier removal function that takes the fact that dose response curves for reactive compounds have a negative slope; the outlier removal function removes obvious outliers (e.g. points above 1.25 after normalization), as well as points that increase the positivity of a slope.

3. Removed misplaced visMatrices function
