// Parse out and break off the issue number
// Try to find the volume with a generated title-volume key (comixology_key)    
// If we can't find the volume
    // Parse the title
    // Parse the volume number (assuming 1)
    // Find the title
        // If no title found, create one
    // Find the title->volume
        // If no title->volume found, create one
// Check for an existing issue
    // If no issue, create a new one
    // If issue found, update with Comixology data (description, release date, price [if missing], comixology_url)
