gSchool Ruby assessment

You work for a book company that publishes poems. You just inherited a treasure trove of poems in the public domain. Your job is to provide some stats about the poems.

Each poem file looks like this:

In Possum Land
Henry Lawson

In Possum Land the nights are fair,
the streams are fresh and clear;
no dust is in the moonlit air;
no traffic jars the ear.

With Possums gambolling overhead,
'neath western stars so grand,
Ah! would that we could make our bed
tonight in Possum Land

The files contain:

A title
An author
A blank line
The poem
Each verse is separated by a blank line

Challenge

Write library code that can:

Go through every file in a given directory (see http://www.ruby-doc.org/core-2.1.2/Dir.html#method-c-glob)
Read each file
Parse the title, author and verses
Generate a hash like so:

{
  "Henry Lawson" => {
    "In Possum Land" => {
      verses: 2,
      lines: 8,
    },
    "I'll Tell You What You Wanderers" => {
      verses: 1,
      lines: 8,
    },
  },
  "Robert Lee Frost" => {
    "The Lockless Door" => {
      verses: 5,
      lines: 20, 
    }
  }
}

The number of lines should reflect the number of non-blank lines. So the following poem would have 8 lines:

In Possum Land the nights are fair,
the streams are fresh and clear;
no dust is in the moonlit air;
no traffic jars the ear.

With Possums gambolling overhead,
'neath western stars so grand,
Ah! would that we could make our bed
tonight in Possum Land
