## =================== INITIATE =================== ##

## 1. Make new instance:

		// $sap_stats = new CSVParser;

## 2. Set source file (CSV) either local or remote (e.g. dropbox public folder or google spreadsheet)

	# e.g. $source_file = 'https://docs.google.com/spreadsheet/pub?key=0AuzaQN6Gty3IdFdqR3RJandpVDBaYWMzXzVnM2xHakE&single=true&gid=0&output=csv';
	# e.g. $source_file = 'https://dl.dropboxusercontent.com/u/3542031/test.csv';
	# if not specified, defaults to test.csv in assets folder
		// $sap_stats->setInputFile($source_file);

## 3. Set output style (CSS) - name of file without ".css"

	# e.g. "fancy", "bootstrap.min"
	# if not specified, defaults to "simple"
		// $sap_stats->setOutputStyle('bootstrap.min');

## ============== AVAILABLE OUTPUTS ============== ##

## Total of specified column (first column = 1, second column = 2, etc)

	# Either prints :
		// $sap_stats->printColumnTotal(2);

	# or gets :
		// $sap_stats->getColumnTotal(2);

## Formatted HTML table of CSV data

	# Either prints:
		// $sap_stats->printTable();

	# or gets :
		// $sap_stats->getTable();

## ============ OTHER PUBLIC FUNCTIONS ============ ##

## printVars : prints the currently selected style and input file (for testing)

		// $sap_stats->printVars();
