set of autobox methods to transform arrays and hashes

 autobox provides the ability to call methods on native types, e.g. strings,
 arrays, and hashes as if they were objects.
 .
 autobox::Core provides the basic methods for Perl core functions like uc,
 map, and grep.
 .
 This module, autobox::Transform, provides higher level and more specific
 methods to transform and manipulate arrays and hashes, in particular when the
 values are hashrefs or objects.
