Add method to programmatically populate the Dim Loader with requirements

[aschaal]

From @JTiefnig:

Currently, the Loader class is intended exclusively for loading data from Dim files and was not designed to be programmatically populated with data.

A mechanism shall be implemented to programmatically load requirement data into the loader, either by adding elements to the original data or by incorporating additional requirements.

Therefore, the Loader class must be fully initialized without the need for calling the load method, achieved, for example, through an init method.

Example:

    class Reqirement_Container
      attr_accessor :original_data, :all_attributes, :base_dir

      def initialize(base_directory)
        @base_dir = base_directory
        @original_data = {}
        @all_attributes = ::Dim::Requirement::SYNTAX
      end

      def add_attribute(attribute)
        @all_attributes.merge!(attribute)
      end

      def add_module(moduleName, module_data = {})
        filename = File.join(@base_dir, moduleName)
        module_data.merge!({"module" => moduleName })
        @original_data[filename] = module_data
        return filename
      end

      def requirements
        @original_data.map do |filename, data|
          modulename = data.fetch("module", "")
          origin = ""
          category = ""
          linenumber = 0
          data.map do |id, attr|
            Dim::Requirement.new(id, modulename, filename, attr, origin, self, category, linenumber, @all_attributes)
          end
        end.flatten
      end
    end
