This new package reimplements the previous classes TMatrix and TMatrixD.
The new classes should be back compatible with the previous version except
the function GetElements.
New classes have been introduced for symmetric matrices,
lazy matrices.
New algorithms (LU, SVD) have been introduced.
A new test suite test/stressLinear.cxx is introduced.
A complete description of this package will be posted in the coming days.
The classes are well documented in the implementation headers.
