 * Change the API to allow only on kind of transformation, not a list of transformations. See issue [#164](https://github.com/norlab-ulaval/libpointmatcher/issues/164).
 * Migrate ffrom yaml-cpp 0.3 to 0.5
 * Fix portability problem with FileLogger on Windows
 * Support for OpenMP parallel computing
 * Handle larger point clouds (100 million points and more)

Already implemented in the current master:

 * add a new OutlierFilter: RobustWelschOutlierFilter (for robust cost function using Welsch weighting).
 * Add a new ErrorMinimizer: PointToPointSimilarityErrorMinimizer (rotation + translation + scale)
 * Add a new Transformation: SimilarityTransformation.

 * Add support for PCL ([Point Cloud Library](http://pointclouds.org/)) data format: PCD (April 2014, thanks to Samuel Charreyron) 
 * Improve *.vtk legacy format to handle UNSTRUCTURED_GRID format (April 2014, thanks to Samuel Charreyron)
 * New ErrorMinimizer producing covariance matrix (1 April, 2014, thanks to Francisco J Perez Grau)
