Adding language switching and minimize button (#25)

* Initial Push

Inititial project state

* Static demo version

* static demo site - added variables

a

* first_implementation

* Updated UI, Improved Style to be more "Reactly", added Functionality

* add parsing functions

* change folder

* Import/Export Prototype

* Adding "reactjs-popup" to package,json

* Adding GLPK source

* Rough implementation of solver + example

* Show solution in output

* example 2 + popup lib

* removing import button

This feature won't be needed in this state of the project and might come back later. Right now it serves no functional purpose.

* Removing "Popout" button

This feature won't be needed in this state of the project and might come back later. Right now it serves no functional purpose.

* Updating Logs

Now the site displays all logs created with customLog(STRING). Logs can be cleared with customLogClear();

* Adding walltime

Can be called using:

Start:
function walltimeStart() {
returns Date.now();

Stop:
function walltimeStopAndPrint(startpoint: number) {
Add startpoint as argument.
It prints the elapsed time using customLog()

* Adding duals ouput

* Adding glpk.js package

required dependency

* adding LP format export and fixing a few errors

* fixing further errors

* adding automatic build

* Moving files to correct folders

* Update nextjs.yml

* Updating README and .gitignore

README:
- added installation instructions
- added troubleshooting

gitignore:
- skipping Writerside and .idea folders

* Update LICENCE.txt

We are required to use the same license. See https://github.com/hgourvest/node-glpk/blob/master/LICENSE

* Updating icon

* Adding RegEx input checks and updating text box explanations

* Update README.md

* Updatint License

* Fixing design issue and updating license link

* Fixing typo in log

* Fixing white mode
