Functions
DatasetInfo *	ReadDataset (bool isBinaryFile, bool isStringFile, char *filename, double minSupPercent, StringMap *&custStrMap, StringMap *&transStrMap, StringMap *&itemStrMap)
	It reads the input file and finds the frequent-1 itemsets.
int	compare (const void *arg1, const void *arg2)
void	LogStdoutSequence (const int c)
void	LogFileSequence (const int c)
void	LogSequence (const int c)
void	CreateOrBitmap (SeqBitmap **f1, int *indexList, int indexLength, SeqBitmap *&orBitmap)
	OR's all of the frequent-1 itemset bitmaps together This is used to create the refBitmap for bitmap compression.
void	Compress (SeqBitmap *refBitmap, SeqBitmap *tempAndBitmap, SeqBitmap *&returnBitmap, SeqBitmap **f1, SeqBitmap **newF1, int *indexList, int indexLength)
	Perform compression on a sequence bitmap.
void	FindSequentialPatterns (TreeNode *curNode)
	A recursive call that goes down the search lattice to find sequential patterns.
void	StartMining (DatasetInfo *info)
	Start the mining algorithm by generating the initial TreeNode to start recursing from.
void	PrintError ()
int	main (int argc, char **argv)
Variables
ofstream	summaryFile
int	minSup
	min sup as a transaction count
TreeNode **	nodeBuff
	node buffer
int *	tempIndexList
	stored the result of combining i-list and s-list
bool *	indexExists
	for combining i-list and s-list
ofstream	outFile

int	minCompSize
	no compression will be done if the bitmap size (_sizeShort) is small than this
double	emptySpaceRatio
	the ratio at which we compress the bitmaps
int	compLevel
	Used to test whether compression should be done at every level.
int	totalCust
int	testCount = 0
