A method to make named parameters strongly defined. 

Added a method that processes named parameters and ensures all mandatory ones
exist and substitutes missing optional ones with default values.  This makes
named parameters strongly defined and easier to read.

Thanks to http://developinginthedark.com/posts/cakephp-tip-1-named-parameters
for the idea.
