# The type of rating that can be assigned.  This is an enumeration which
# consists of a pre-determined set of possible rating values.  Each value has
# the following attributes:
# * +name+ - The actual name to refer to the value as
# * +value+ - The numeric value of the rating (higher is better)
# 
# Values should normally be referred to by name.  For example,
# 
#   RatingValue['poor']       # => #<RatingValue id: 1, name: "poor", value: 1>
#   RatingValue['excellent']  # => #<RatingValue id: 5, name: "excellent", value: 5>
