til::sparse_vector
A class that mimic the behavior of std::vector but with a storage policy focused on sparse data...

til::sparse_vector::getMap
Map & getMap()
Returns the internal data.

til::is_nan
bool is_nan(const numeric_array< T, D > &a)
Check that numeric_array does not contain any NAN TODO: Actually, is_nan should be a functor...
