------------------------------------------

I can contribute this feature to https://github.com/apache/commons-lang/ if you'll review
it. :)

> In Spring's [org.springframework.util.ObjectUtils|https://github.com/spring-projects/spring-framework/blob/master/spring-core/src/main/java/org/springframework/util/ObjectUtils.java] there's
a null-safe [isEmpty method|https://github.com/spring-projects/spring-framework/blob/04141dee65ff5e078e2a9137ff7052351f6ab66c/spring-core/src/main/java/org/springframework/util/ObjectUtils.java#L134] that
checks whether an object is empty based on its type. If the object is a string it calls String.isEmpty,
if it's a collection it calls Collection.isEmpty, etc. I think a similar method would be a
really nice addition to org.apache.commons.lang3.ObjectUtils, as it would allow people like
me to use it without adding a dependency to Spring or re-implementing the method in our code.
