BASIC USAGE:
include "lorem-phpsum.php";

echo phpsum(); // print 100 random words
echo phpsum(20); // prints 20 random words
echo phpsum(20, 40); // prints a random number of 20 to 40 words
echo phpsum(20, 40, 2); // prints a random number of 20 to 40 words in 2 paragraphs
echo phpsum(20, 40, 2, 4); // prints a random number of 20 to 40 words in a random number of 2 to 4 paragraphs


ADVANCED USAGE:
include "lorem-phpsum.php";

	'duplicateParagraphs' => 'false', 	// should all paragraphs be identical?
	'lorem' => 'true', 					// should we begin with "Lorem ipsum..."?
	'periods' => 'true', 				// should we include periods between sentences?
	'caps' => 'true', 					// should each sentence start with a capital letter?
	'html' => 'true', 					// should we include <p> tags between paragraphs? otherwise use tabs and line breaks
	'doubleSpace' => 'false', 			// should we include double spaces between sentences?
	'minCharsInWords' => 2,
