In ElementaryUtils:
- Use command "executable" in the Ant scripts instead of the deprecated command "command".

In NumA++:
- Overload functors to allow call without parameters.
- Restructuring of folders for Functors.
- Rename LinearSystem to LinAlgUtils and add rank routine.
- New EigenUtils to encapsulate conversions to or from Eigen. In order for PARTONS to be independent of Eigen.
- New methods in MatrixD (appendLine, etc).
- New constructors for VectorD.
- New static method in Interval to compute nodes.

In NumA++_Test:
- New tests for Eigen.

In PARTONS:
- New modules IncompleteGPDModule and RadonInverseModule.
- First method for Radon inversion: Random brute force with constant piecewise functions (RandBFConstPW). Still no inversion, only matrix construction.
- Addition of DDGauge type and modification of DDType.
- New OverlapMMR15 model.
