There are sometimes you have data that may contain empty strings, null values, or empty arrays. In these cases it would be nice to be able to filter out these empty values similar to the
collect()->filter()method.This PR implements a
filter_emptymodifier. I was specific in how I named it so that people hopefully won't confuse it with thecollect()->filter()method as that method allows you to pass a custom callback to perform extra filtering which this modifier does not support.Let me know what you think.
