+=head1 NAME
+
+SL::ReportGenerator.pm: the Lx-Office way of getting data in shape
+
+=head1 SYNOPSIS
+
+ my $report = SL::ReportGenerator->new(\%myconfig, $form);
+ $report->set_options(%options); # optional
+ $report->set_columns(%column_defs);
+ $report->set_sort_indicator($column, $direction); # optional
+ $report->add_data($row1, $row2, @more_rows);
+ $report->generate_with_headers();
+
+This creates a report object, sets a few columns, adds some data and generates a standard report.
+Sorting of columns will be alphabetic, and options will be set to their defaults.
+The report will be printed including table headers, html headers and http headers.
+
+=head1 DESCRIPTION
+
+Imagine the following scenario:
+There's a simple form, which loads some data from the database, and needs to print it out. You write a template for it.
+Then there may be more than one line. You add a loop in the template.
+Then there are some options made by the user, such as hidden columns. You add more to the template.
+Then it lacks usability. You want it to be able to sort the data. You add code for that.
+Then there are too many results, you need pagination, you want to print or export that data..... and so on.
+
+The ReportGenerator class was designed because this exact scenario happened about half a dozen times in Lx-Office.
+It's purpose is to manage all those formating, culling, sorting, and templating.
+Which makes it almost as complicated to use as doing the work for yourself.
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item new \%myconfig,$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 this data has to be already sorted.
+ReportGenerator does no sorting on its own, only 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 '<br>'. 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. Is invoked by the pdf render functions.
+
+=item generate_csv_content
+
+The CSV generation function. Uses XS_CSV to parse the information into csv.
+
+=item render_pdf_with_pdf_api2
+
+PDF render function. Uses PDF module.
+
+=item render_pdf_with_html2ps
+
+PDF render function. Uses html2ps to render.
