If OpenIntToDoubleHashMap returns NaN for non-existent keys, then the
Sparse Matrix could check for NaN to return 0 to its client.

I am still working through this class and the sparse matrix class that
it was extracted from (thanks, Ismael and Sugit!), so I am not sure if
changing this would cause problems, but the current setup (returning 0
for missing keys) limits usefulness of this class. I see how this is
convenient for sparse matrices; but I would see NaN as a more natural
return value for non-existent keys in the general case.
Alternatively, I guess we could add another method get(int key,
double missingReturn).
Thoughts?
