Mapper to project data onto SVD components estimated from some dataset.
Initialize the SVDMapper
Methods are prefixed correspondingly. forward/reverse operate on the entire dataset. get(In|Out)Id[s] operate per element:
forward in ---------> out <--------/ reverse
Subclasses should define 'dsshape' and 'nfeatures' properties that point to getInShape and getOutSize respectively. This cannot be done in the baseclass as standard Python properties would still point to the baseclass methods.
Does nothing.

Project a 2D samples x features matrix onto the SVD components. :Parameters: data: array Data arry to map demean: bool Flag whether to substract the training data mean before mapping. XXX: Not sure if this is the right place. Maybe better move to constructor as it would be difficult to set this flag. :Returns: NumPy array
