Merge pull request #124 from eodus/plotfix_factorv

Fix factorvectors plot for 1D-SSA case
Add deprecation mechanism and convert 'lambda' to 'sigma'.
dot'ify internal function
Introduce new "decomposition" object.
Switch stuff to it. No functionality change.
Normalize the internal .F accessor usage
Make first use of the decomposition stuff: Toeplitz SSA.
Also, make sure the helpers are unaware about the exact layout of the object.
Make U, V, sigma generics. Provide implementations for SSA objects and for decompositiontions
itself.
Grab the decomposition for forecast
Apparently, forecasts require orthonomal bases.
Introduce {row,col}span methods
