bug #1154 : move to dynamic scheduling for spmv products.

Refactoring of the cost model:
...
- Dynamic is now an invalid value
- introduce a HugeCost constant to be used for runtime-cost values or arbitrarily huge cost
- add sanity checks for cost values: must be >=0 and not too large
This change provides several benefits:
- it fixes shortcoming is some cost computation where the Dynamic case was not properly handled.
- it simplifies cost computation logic, and should avoid future similar shortcomings.
- it allows to distinguish between different level of dynamic/huge/infinite cost
- it should enable further simplifications in the computation of costs (save compilation time)

Since there is no reason for evaluators to be nested by reference, let's remove the evaluator<>::nestedType indirection.

Index refactoring: StorageIndex must be used for storage only (and locally when it make sense). In all other cases use the global Index type.

bug #877 , bug #572 : Introduce a global Index typedef. Rename Sparse*::Index to StorageIndex, make Dense*::StorageIndex an alias to DenseIndex. Overall this commit gets rid of all Index conversion warnings.
