    # Does a count on the query

    # example:
    #  User.count(:age => 20)
    #
    # is the same as:
    #  User.where(:age => 20).count
    #
    # if the key :conditions is present it will fall back to legacy
    #
    # @param [Hash]
    #   Optional follows same convention as {#all}
    # @return [Integer]
