CONCEPT

    The follow is a short and simple overview of the strategy and syntax
    used by Data::Seek to query complex data structures. The overall idea
    behind Data::Seek is to flatten/fold the data structure, reduce it by
    applying a series patterns, then, unflatten/unfold and operate on the
    new data structure. The introspection strategy is to flatten the data
    structure producing a non-hierarchical data structure where its keys
    represent endpoints (using dot-notation and colons to separate (and
    denote) nested hash keys and array indices respectively) within the
    structure.

ENCODING

    During the processing of flattening a data structure with nested data,
    the following data structure would be converted into a collection of
    endpoint/value pairs.

        {
            'id' => 12345,
            'patient' => {
                'name' => {
                    'first' => 'Bob',
                    'last'  => 'Bee'
                }
            },
            'medications' => [{

# DESCRIPTION

Data::Seek is used for querying complex data structures. This module allows you
to select and return specific node(s) in a hierarchical data structure using a
simple and intuitive query syntax. The results can be returned as a list of
values, or as a hash object in the same shape as the original.

# ENCODING

During the processing of flattening a data structure with nested data, the
following data structure would be converted into a collection of endpoint/value
pairs.

    {
        'id' => 12345,
        'patient' => {
            'name' => {
                'first' => 'Bob',
                'last'  => 'Bee'
            }
        },
