EngineTests and ffpack

[jakobkroeker]

linear algebra probably not explicitly tested:
(holds for appropriate rings; I did not check if the routines connected to M2 )

• rowReducedEchelonForm()
• solveInvertible()
• addMultipleTo()
• subtractMultipleTo()
• eigenvalues()
• eigenvaluesHermitian()
• leastSquares()
• clean()
• increase_norm()

basic AringZZpFFPack ring operations not explicitly tested:

• is_zero()
• getGenerator()
• field()
• computeHashValue( )
• text_out( )
• elem_text_out()
