getNestedValue - Change method name?

I thought it would be helpful to have a method in lodash which will allow developers to retrieve a nested value from a complex object safely. 

Instead of the following: 
```
if ( hero && hero.costume && !_.isEmpty(hero.costume.mask) ) {
     return hero.custome.mask;
}
```

You could have: 
```
return _.getNestedValue(hero, 'hero.costume.mask');
```
