/*	This file is exclusively for generating reports to help assist forum
	administrators keep track of their forum configuration and state. The
	core report generation is done in two areas. Firstly, a report "generator"
	will fill context with relevant data. Secondly, the choice of sub-template
	will determine how this data is shown to the user. It has the following
	functions:

	void ReportsMain()
		- requires the admin_forum permission.
		- loads the Reports template and language files.
		- decides which type of report to generate, if this isn't passed
		  through the querystring it will set the report_type sub-template to
		  force the user to choose which type.
		- when generating a report chooses which sub_template to use.
		- depends on the cal_enabled setting, and many of the other cal_
		  settings.
		- will call the relevant report generation function.
		- if generating report will call finishTables before returning.
		- accessed through ?action=admin;area=reports.

	void xxxxxxReport()
		- functions ending with "Report" are responsible for generating data
		  for reporting.
		- they are all called from ReportsMain.
		- never access the context directly, but use the data handling
		  functions to do so.

	void newTable(string title = '', string default_value = '',
			string shading = 'all', string width_normal = 'auto',
			string align_normal = 'center', string width_shaded = 'auto',
			string align_shaded = 'auto')
		- the core of this file, it creates a new, but empty, table of data in
		  context, ready for filling using addData().
		- takes a lot of possible attributes, these have the following effect:
			+ title = Title to be displayed with this data table.
			+ default_value = Value to be displayed if a key is missing from a
			  row.
			+ shading = Should the left, top or both (all) parts of the table
			  beshaded?
			+ width_normal = width of an unshaded column (auto means not
			  defined).
			+ align_normal = alignment of data in an unshaded column.
			+ width_shaded = width of a shaded column (auto means not
			  defined).
			+ align_shaded = alignment of data in a shaded column.
		- fills the context variable current_table with the ID of the table
		  created.
		- keeps track of the current table count using context variable
		  table_count.

	void addData(array inc_data, int custom_table = null)
		- adds an array of data into an existing table.
		- if there are no existing tables, will create one with default
		  attributes.
		- if custom_table isn't specified, it will use the last table created,
		  if it is specified and doesn't exist the function will return false.
		- if a set of keys have been specified, the function will check each
		  required key is present in the incoming data. If this data is missing
		  the current tables default value will be used.
		- if any key in the incoming data begins with '#sep#', the function
		  will add a separator accross the table at this point.
		- once the incoming data has been sanitized, it is added to the table.

	void addSeparator(string title = '', int custom_table = null)
		- adds a separator with title given by attribute "title" after the
		  current row in the table.
		- if there are no existing tables, will create one with default
		  attributes.
		- if custom_table isn't specified, it will use the last table created,
		  if it is specified and doesn't exist the function will return false.
		- if the table is currently having data added by column this may have
		  unpredictable visual results.

	void finishTables()
		- is (unfortunately) required to create some useful variables for
		  templates.
		- foreach data table created, it will count the number of rows and
		  columns in the table.
		- will also create a max_width variable for the table, to give an
		  estimate width for the whole table - if it can.

	void setKeys(string method = 'rows', array keys = array(),
			bool reverse = false)
		- sets the current set of "keys" expected in each data array passed to
		  addData. It also sets the way we are adding data to the data table.
		- method specifies whether the data passed to addData represents a new
		  column, or a new row.
		- keys is an array whose keys are the keys for data being passed to
		  addData().
		- if reverse is set to true, then the values of the variable "keys"
		  are used as oppossed to the keys(!)
