Tool Evaluate Statistics for Grids

Calculates statistical properties (arithmetic mean, range, variance, standard deviation, percentiles) on a cell-wise base. This tool takes input about basic statistical information as it can be collected with the 'Build/Add Statistics for Grids' tools. These three tools (build, add, evaluate) have been designed to inspect a large number of grids that could otherwise not be evaluated simultaneously due to memory restrictions.
