Clearly seperate original content from external libraries and conform to external software license terms

[Kevin-Mattheus-Moerman]

IMPORTANT This code base contains codes obtained from DistMesh and is currently not complying with its license terms:

under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version

• [x] I propose you create a folder called code_ext and place within it any codes which is not your original work. For the DistMesh related components would create a folder called DistMesh in the code_ext folder. Then copy all required source code components into that folder and include a LICENSE file describing the license for DistMesh. I would do the same (dedicated folders with license files) for all other external packages/codes included. So, in short, clearly separate your codes from externally obtained codes. It is not permitted to share codes from others without complying to the license terms.

Note that the GPL license for DistMesh contains:

But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Hence if you include DistMesh with FlexWingRom then:

• [x] FlexWingRom will also need to adopt a GPL license. I suggest GPLv3, as long it is compatible.

I have also found the following with its own license terms: https://uk.mathworks.com/matlabcentral/fileexchange/28337-cosspace

Please do the above (separate codes and adhere to license terms) for absolutely all types of external codes/libraries included.
