Adjusted Highest Points Near Location Tool

Made adjustments to the tool that so that I no longer receive Errors
999999, 010213, 010325, 010067. Additionally, I added to the tool to get
a manageable output. Before I added to the model, I would get a return
of multiple points with the same attribution due to elevation
similarities. Basically, I add a Mean Center tool to remove multiple
point and create a singular center point. Also added function to add
elevation values within the attribute table.
