Added commands to makefile for Install & Uninstall

[Wingie]

make install will install libraries in /usr/share/ngs/
make uninstall will delete contents of the above folder

Thanks!

Could you please adjust the commands as per https://www.gnu.org/prep/standards/html_node/Directory-Variables.html ? default prefix would be /usr/local and so on. Note no trailing slash, please add it in the cp commands. I guess the location of ngs files should also be passed to ngs.c and compiled in as one of the places to search, probably the last one.

Optional / later: It would be also nice to add a test to .travis.yml that would make sure the installation went OK... and removal.

Interesting read that was.
if i put the files in /usr/local/share/ngs/ the binary no longer finds it when invoked with ./ngs demo/ec2din.ngs

Yep. I've edited my comment above so you probably missed it: you should also modify ngs.c to look at the location specified at build time.

Merged with modifications. Needs testing but I can't do it right now.
