Template:Spell with no purchasable scroll list by Class phantom

Purpose

 * Used as a transform/phantom template by Template:Spell with no purchasable scroll list by Class
 * Determines if no purchasable scroll exists for a given spell and generates output based on results
 * (Primary benefit is to be used by classes that scribe spells to help decide which spells to learn when leveling)

Usage (outputs)

 * Output will be a set of thirteen or fourteen table data cells
 * Page name (as identified by the argument passed in through %TITLE%)
 * Spell name (as calculated by existence of either the "name" argument passed in through dpl, Page name if "name" parameter empty)
 * One cell for each class to represent the level of the spell for the corresponding class (Alc,Art,...)
 * Cell containing a table of all the (non purchasable) scrolls that exist that cast the spell (if no scrolls exist, no cell data will exist here)

Examples
{| class="wikitable" |-       ! code ! result |-       |          |    |-        |          |

|-       |          |
 * }

Uses

 * Template:GetPageTemplateParameter used to retrieve class based level data based on spell
 * (spell level data retrieval log may (?) be able to be refactored to use dpl to pull all data points in one pass)

Categorization

 * Add page to Category:Pages with invalid template arguments if any parameter value is identified as invalid
