Adjustments to multiple tools within the MAoT Toolbox

Made adjustments to the following models within the MAoT toolbox:
Find Local Peaks
Highest Points Near Locations Modified
Linear Line of Sight Modified
Lowest Points Near Locations Modified
Range Fan From Bearing and Traversal with Visibility Modified
Artillery Slope Tint Modified

The ones that have the modified after the name are the orginal tool with
changes. The changes include the ability to add layer dataset. This
allows customers to add not only local data, but also serviced data that
is within the map document. This should also allow the user to process
tools with the processing templates within the elevation services.
