+
+This creates a report object, sets a few columns, adds some data and generates a standard report.
+Sorting of columns will be alphabetic, and options will be set to their defaults.
+The report will be printed including table headers, html headers and http headers.
+
+=head1 DESCRIPTION
+
+Imagine the following scenario:
+There's a simple form, which loads some data from the database, and needs to print it out. You write a template for it.
+Then there may be more than one line. You add a loop in the template.
+Then there are some options made by the user, such as hidden columns. You add more to the template.
+Then it lacks usability. You want it to be able to sort the data. You add code for that.
+Then there are too many results, you need pagination, you want to print or export that data..... and so on.
+
+The ReportGenerator class was designed because this exact scenario happened about half a dozen times in kivitendo.
+It's purpose is to manage all those formating, culling, sorting, and templating.
+Which makes it almost as complicated to use as doing the work for yourself.
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item new \%myconfig,$form,%options
+
+Creates a new ReportGenerator object, sets all given options, and returns it.
+
+=item set_columns %columns
+
+Sets the columns available to this report.
+
+=item set_column_order @columns
+
+Sets the order of columns. Any columns not present here are appended in alphabetic order.
+
+=item set_sort_indicator $column,$direction
+
+Sets sorting ot the table by specifying a column and a direction, where the direction will be evaluated to ascending if true.
+Note that this is only for displaying. The data has to be presented already sorted.
+
+=item add_data \@data
+
+=item add_data \%data
+
+Adds data to the report. A given hash_ref is interpreted as a single line of data, every array_ref as a collection of lines.
+Every line will be expected to be in a kay => value format. Note that the rows have to be already sorted.
+ReportGenerator does only colum sorting on its own, and provides links to sorting and visual cue as to which column was sorted by.
+
+=item add_separator
+
+Adds a separator line to the report.
+
+=item add_control \%data
+
+Adds a control element to the data. Control elements are an experimental feature to add functionality to a report the regular data cannot.
+Every control element needs to set IS_CONTROL_DATA, in order to be recongnized by the template.
+Currently the only control element is a colspan element, which can be used as a mini header further down the report.
+
+=item clear_data
+
+Deletes all data filled into the report, but keeps options set.
+
+=item set_options %options
+
+Sets options. For an incomplete list of options, see section configuration.
+
+=item set_options_from_form
+
+Tries to import options from the $form object given at creation
+
+=item set_export_options $next_sub,@variable_list
+
+Sets next_sub and additional variables needed for export.
+
+=item get_attachment_basename
+
+Returns the set attachment_basename option, or 'report' if nothing was set. See configuration for the option.
+
+=item generate_with_headers
+
+Parses the report, adds headers and prints it out. Headers depend on the option 'output_format',
+for example 'HTML' will add proper table headers, html headers and http headers. See configuration for this option.
+
+=item get_visible_columns $format
+
+Returns a list of columns that will be visible in the report after considering all options or match the given format.
+
+=item html_format $value
+
+Escapes HTML characters in $value and substitutes newlines with '
'. Returns the escaped $value.
+
+=item prepare_html_content $column,$name,@column_headers
+
+Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked.
+Should not be called extrenally, since all render and generate functions invoke it anyway.
+
+=item generate_html_content
+
+The html generation function. Is invoked by generate_with_headers.
+
+=item generate_pdf_content
+
+The PDF generation function. It is invoked by generate_with_headers and renders the PDF with the PDF::API2 library.
+
+=item generate_csv_content
+
+The CSV generation function. Uses XS_CSV to parse the information into csv.

+
+=head1 CONFIGURATION
+
+These are known options and their defaults. Options for pdf export and csv export need to be set as a hashref inside the export option.
+
+=head2 General Options
+
+=over 4
+
+=item std_column_visibility
+
+Standard column visibility. Used if no visibility is set. Use this to save the trouble of enabling every column. Default is no.
+
+=item output_format
+
+Output format. Used by generate_with_headers to determine the format. Supported options are HTML, CSV, and PDF. Default is HTML.
+
+=item allow_pdf_export
+
+Used to determine if a button for PDF export should be displayed. Default is yes.
+
+=item allow_csv_export
+
+Used to determine if a button for CSV export should be displayed. Default is yes.
+
+=item html_template
+
+The template to be used for HTML reports. Default is 'report_generator/html_report'.
+
+=item controller_class
+
+If this is used from a C based controller class, pass the
+class name here and make sure C is
+used in the controller. That way the exports stay functional.
