tiny modifications to resolve compiling errors with gcc (Suse Linux, v4.7.1)
added reference to mailing list
added the method itk::StatisticalModel::ComputeCoefficientsForSample , for consistency of the interface

however, there is still a question about the input type, which is not a 'DataSample' but a 'Dataset'
Merge branch 'master' of github.com:statismo/statismo
added a method ComputeCoefficientsForDataSample, to enable the computation of the coefficients directly from the training samples of the DataManager

-> need to check for the consistency of the interface & terminology, between Samples and Dataset
Added a dimensionality reduction functionality to all model builders, and an additional field in the ModelInfo to store the total variance in the data - this allows to keep track of things, at least indirectly
fixed the Load method, which didn't handle the mask properly
fixed call
fixed minor issue
test commit - just small doc update
