Webserver handling basic HTTP GET requests.

Usage:

$ ./server <port> <directory>

e.g.

$ ./server 8888 webpages

Note: If we want to access a site with path webpages/name_of_website/index.html, there should be an entry in /etc/hosts file of form

...
127.0.0.1	name_of_website
...

so that we can access it with http://name_of_website:8888/index.html
