* 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
-- roundtripping namespaces requires modifications of the parser used for the entire worksheet as there does not appear to be a way to track the namespace changes without listening/registering for the event. This (ofcourse) breaks lots of other things...
-- custom_heights was the only test sheet where the integral value was being saved with a trailing ".0"
-- Updated tests to expect the new values
-- added the new property "defaultColWidth"
-- tolower takes chars and returns chars, types are int because C only deals with ints
-- format parameter is size_t but there is no std parsing function that returns size_t. stoull is used instead as the widest alternative, and then the cast is applied to suppress the conversion warnings
-- to encode: copy the string into unicodelookup.com. Take the hex representation and pad to 4 characters with '0's, prefixing each character with '\u'
-- sqref is a block of selected cells containing the active_cell (normally is just == active_cell)
-- active cell is the selected vell in this selection/view/pane
-- inactive selections use the top-left cell as the active_cell
-- NOTE: It doesn't seem likely that these should be 'A1' in all cases (set to 'A1' because current tests demanded it). Purpose of this parameter needs clarification
-- NOTE: [xlnt::selection] needs appropriate ctor's once the purpose of the parameters can be clarified
