	PCATransformer (bool debug=false)
	Default constructor.
void	computePCA (Corpus *corpus)
	Computes the PCA from a corpus.
bool	load (string filename)
	Load a previously computed PCA.
bool	save (string filename)
	Save the computed PCA.
vector< float >	transform (vector< float > input)
	Transform a vector in the new coordinates.
Corpus *	transform (const Corpus &corpus, int coord=2)
	Transform a corpus to a new one (keeping only the 'coord' first coordinates). The returned corpus has to be deleted by the user.

Static Public Member Functions
static string	serializeMatrix (MatrixXf m)
	Serialize a matrix : write it down as a human-readable string.
static MatrixXf	readMatrix (string m, int nbRows=1, int nbCols=1)
