# We over-ride methods on CatalogController simply by include'ing this
# module into CatalogController, which this plugins setup will do.
#
# This works ONLY becuase the methods we're over-riding come from
# a module themsleves (SolrHelper) -- if they were defined on CatalogController
# itself, it would not, and we'd have to use some ugly monkey patching
# alias_method_chain instead, thankfully we do not.
