Computes the average of a variable along each individual line of the specified user line cloud, and returns a location-dependent result.
For example, the expression lineCloudAve(phi)@MyCloud
        would cause the following to happen during its evaluation:
The mesh based variable
phiwould be interpolated onto the line points in user line cloudMyCloud.For each line in the line cloud, the values of phi on the line points are averaged, and the average value is stored at each of the line points.
The line-averaged values of phi are then scattered outward from each line to the surrounding mesh, to produce a field of line averaged values, accessible as the function result.
In this example, the MyCloud user line cloud contains
        all of the settings that control the above process. For example, if the
        user line cloud is defined using the From Boundaries
        option, the result of the lineCloudAve function is a field
        of values available on or near the specified boundaries. The averaging is controlled by
        the Line Averaging settings in the user line cloud definition.
        The resulting field is interpolated onto the mesh vertices using the Line Interpolation
        settings in the user line cloud definition. See
        User Line Cloud in the CFX-Pre User's Guide.
