a9232af845 Introduce a variable_or_fixed<N> proxy returned by fix<N>(val) to pass both a compile-time and runtime fallback value in case N means "runtime". 
This mechanism is used by the seq/seqN functions. The proxy object is immediately converted to pure compile-time (as fix<N>) or pure runtime (i.e., an Index) to avoid redundant template instantiations.

752bd92ba5 Large code refactoring: 
- generalize some utilities and move them to Meta (size(), array_size())
 - move handling of all and single indices to IndexedViewHelper.h
 - several cleanup changes

87963f441c Fallback to Block<> when possible (Index, all, seq with > increment). 
This is important to take advantage of the optimized implementations (evaluator, products, etc.),
and to support sparse matrices.

58146be99b bug #1004: one more rewrite of LinSpaced for floating point numbers to guarantee both interpolation and monotonicity. 
This version simply does low+i*step plus a branch to return high if i==size-1.
Vectorization is accomplished with a branch and the help of pinsertlast.
Some quick benchmark revealed that the overhead is really marginal, even when filling small vectors.
