Wrap lines to 80 We wrapped lines to make easier the source easier to read, and to have more manageable diffs. This was done with something like: ```sh pandoc --wrap=auto --atx-headers -f markdown -t markdown-fenced_code_attributes+pipe_tables+raw_html+intraword_underscores` ```

Once you have included the PhpSpreadsheet files in your script, but
before instantiating a `Spreadsheet` object or loading a workbook file,
there are a number of configuration options that can be set which will
affect the subsequent behaviour of the script.

Refactor CachedObjectStorage to PSR-16 This drop a lot of non-core features code and delegate their maintainance to third parties. Also it open the door to any missing implementation out of the box, such as Redis for the moment. Finally this consistently enforce a constraint where there can be one and only one active cell at any point in time in code. This used to be true for non-default implementation of cache, but it was not true for default implementation where all cells were kept in-memory and thus were never detached from their worksheet and thus were all kept functionnal at any point in time. This inconsistency of behavior between in-memory and off-memory could lead to bugs when changing cache system if the end-user code was badly written. Now end-user will never be able to write buggy code in the first place, avoiding future headache when introducing caching. Closes #3

By default, PhpSpreadsheet holds all cell objects in memory, but
you can specify alternatives to reduce memory consumption at the cost of speed.
