Find views in view hierarchy that corresponded specified properties. Titanium Alloy.

findViews.js

var findViews = function(where, props, deep) {    
    var ctl = _.where(where.children, props);
    if(deep){
        return _.reduce(where.children, function(memo, view) {
            return memo.concat(findViews(view, props, true));
        }, ctl);
    } else {
        return ctl;
    }
};

do you have a small usage example for this function?
