Intialize a Match object with a record hash of fields you want to match on. Each key in the hash, also has a data hash value for the weight, token, and type.

    match = Ofac::Match.new({:name => {:weight => 10, :token => 'Kevin Tyll'},
        :city   => {:weight => 40, :token => 'Clearwater',     },
        :address => {:weight => 40, :token => '1234 Park St.',    },
        :zip    => {:weight => 10, :token => '33759', :type => :number}})

 data hash keys:
   * <tt>data[:weight]</tt> - value to apply to the score if there is a match (Default is 100/number of keys in the record hash)
   * <tt>data[:token]</tt> - string to match
   * <tt>data[:match]</tt> - set from records hash
   * <tt>data[:score]</tt> - output field
   * <tt>data[:type]</tt> - the type of match that should be performed (valid values are +:sound+ | +:number+) (Default is +:sound+)

  def initialize(stats={})
    @possible_hits = []
    @stats = stats.dup
    weight = 100
    weight = 100 / @stats.length if @stats.length > 0
    @stats.each_value do |data|
      data[:weight] ||= weight
      data[:match]  ||= ''
      data[:type]   ||= :sound
      data[:score]  ||= 0
      data[:token]  = data[:token].to_s.upcase
    end
  end

match_records is an array of hashes.

The hash keys must match the record hash keys set when initialized.

score will return the highest score of all the records that are sent in match_records.
