added two new arguments to fxn_MapColor. The first argument DL specifies the detection limit of the analyte being mapped & adds that info to the legend. The second argumentLegCex allows the user to control the size of the text and bullet points in the legend. The function was also modified such that those lat/lons with non detects show up on the map as a white bullet (and in the legend)
few minor changes to fxn_MapColor
changed the second line of text in the legend so that it is the maximum DL to the first 25% quantile for the first concentration grouping after the non detects
