## Returns a formatted String according to the string pattern.
#
# If +self+ is given as a method, the extracted value will be used.
#
# Imagine this HTML:
# <li>
# <h1>Product</h1>
# <span class="price">23,42€</span>
# </li>
#
# YAML usage example:
#
# selectors:
# items:
# selector: 'li'
# price:
# selector: '.price'
# title:
# selector: h1
# post_process:
# name: template
# string: '%s (%s)'
# methods:
# - self
# - price
#
# Would return:
# 'Product (23,42€)'
class Template
