- Nested unordered_map was the cause of a significant memory/cell spike.
- added cell_reference hash, lookup by cell_reference to make memory usage proportional to cell count only
Issue #300
-- NOTE: construction from no_default currently wont compile so is commented out (L:113)
-- NOTE: dll import/export of template classes is probably unnecessary (the header is already required) and doesn't work in the general case (explicit instantiations are required for at least MSVC)
- hyperlinks to cells and ranges are complete
- hyperlink::display is now set as well as the cell value (in excel these can be different)
-- if a cell is empty, display is equal to value text
-- if a cell has a value, display can be just about anything
- This version copies excel in that display is completely ignored once value is set
- All hyperlink tests are now part of the cell test suite (not the worksheet test suite which the majority were previously located)
-- NOTE: ctor was removed because it can't have been in use, and is duplicated by the overload below it. A pair parameter is only optimal in a very limited number of use cases, and then only slightly over the begin/end overload
* operator-- completes the naive bidirectional iterator requirements
* tests for various construction and assignment behaviours
* tests for iteration and dereferencing behaviours
Users may still want to dereference a const iterator (note: not a const_iterator).
Also use the "reference" typedef to ensure there is only 1 source of information
For rule of 5/0, where no implementation is required, all 5 operations have been declared as defaulted. This is less likely to forget definitions for all 5 if required
- removed forwarding of copy ctor to assignment (which was defaulted already) in favour of defaulted copy ctor
- added defaulted move assignment/ctor and destructor
Changed workbook reference to a pointer to allow tests to compile (reference isn't rebindable so defaulted assignment is equivalent to deleted)

Detailed reasoning for the deprecation is provided by the paper proposing deprecation (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0174r2.html) and a related LWG issue (https://cplusplus.github.io/LWG/issue2438).
This was the only issue preventing a clean compile with VS 15.7.2 with c++17/c++latest set as the target language
The issue could be resolved in two ways. Providing a custom replacement to std::iterator (a very simple structure) or by providing the 5 required typedefs. The only functional difference from my reading is that the typedefs are not immediately available to the implementer with the inheritance. I find the inline typedefs to be clearer hence the selection in this commit
