/**
 * A mapping function to remove an {@link AnalyticsValue} from an {@link AnalyticsValue} or an {@link AnalyticsValueStream}.
 * For each document, the value exists if it doesn't equal the value of the second parameter.
 * 
    
 * The first parameter can be any type of analytics expression. If the parameter is multi-valued, then the return will be multi-valued. (Required)
 * 
    
 * The second parameter, which is the value to remove from the first parameter, must be an {@link AnalyticsValue}, aka single-valued. (Required)
 * 
    
 * The resulting Value or ValueStream will be typed with the closest super-type of the two parameters.
 * (e.g. {@value #name}(int,float) will return a float)
