Fixing indentation after transferring code from another area to here; somehow looses the formatting when pasting. No bother, easy fixed and back to Allman indentation.
This work is to test the new version of xlnt - released today. The installation is much simpler now due to the fact that xlnt no longer relies on third party libraries. This was a great move! I have confirmed that the minimum gcc version required is 6.2.0. work will still continue into exploring how the newest gcc 7.1 will impact xlnt. However, this will be covered under another heading and documentation issue/ticket and will involve installing gcc 7.1 from source and so forth. the documentation in this commit is purely intended to get a new users off and running with xlnt in the shortest possible time and with the least amount of effort.
This has been updated and is ready for deployment. No namespaces used in the header of the code now, just explicit calls in the functions. std::string, std::vector, std::clog, std::endl, xlnt::workbook.
Removing zlib1g, libssl-dev, cryptopp, and expat.
Cryptography now uses public domain code in the source tree (source/detail/cryptography), zlib was replaced with miniz and added to the source tree (source/detail/serialization/miniz.*), and since it's already a part of libstudxml (i.e. a grandchild dependency), xlnt is now using libstudxml's expat (third-party/libstudxml/xml/details/expat).
Removing the -I and -L arguments from the compile command.
I realize that it is unnecessary to specify a list of directories (to be searched) for header files and so forth in the event that the standard xlnt installation process was followed.
Adding the future steps in readiness; waiting for the gcc 6.3.0 to compile - boy that takes a while.
Next step is to run everything after the TODO line and the create a pull request to finalize the documentation
