Better Exception when modifying the collection in the wrong scope

[khalidabuhakmeh]

System.InvalidOperationException: Collection was modified; enumeration operation may not execute. This gets thrown when you are modifying the collection from within a scope. Example:

map.Area<AdjustmentsDashboardController>("dashboards", dashboards =>
{
        // Oooooops!!! Should be using dasbhoards and not map
    map.Path("adjustments").To<AdjustmentsDashboardController>(x => x.Index(null, null));
    map.Path("discounts").To<AdjustmentsDashboardController>(x => x.Index(null, null));
});

This is user error, but should probably give a more helpful exception.
