Title: fix nils: support for nil values

Hi,

I modified the plugin to support null values.
Previous state: both no-value(e.g. a,,c) and ""(e.g. a,"",c ) were treated as empty string
Fix: no-value is treated as nil, and "" is treated as empty string

I reused the "is_nil" method at the CSV::Cell class.
