ICMP_Ping

To compile:

`make`

To run:

Administrator priviledges are required.
`sudo ./bin/main $(HOSTNAME/IP ADDRESS) [-c count] [-i interval] [-t ttl] [-W timeout]` 
HOSTNAME/IP ADDRESS is the command line argument for the server that you are trying to ping.

EXAMPLE: Both 'sudo ./bin/main www.google.com' and 'sudo ./bin/main 172.217.14.68'

Each ping request default has a 2 second timeout, and one ping is sent every second.

Flags:

`   
Flags may be specified in any order, as long as they all come AFTER the hostname/IP address.  
Ensure that there is always a space between the flag and its value.
Flags are case sensitive.

[-c count]  Send exactly *count* ECHO_REQUEST packets. If not specified, ping will send forever

[-t ttl] Set the Time to Live

[-i interval]  Set the interval between packets in seconds

[-W timeout]  Set the time to wait for a response to the ping before giving up in milliseconds
`

To clean:

`make clean`

IPv6 Support

IPv6 address can be read in, but through my testing, only ::1 actually will work.
All other IPv6 will be unable to send through the socket. 
I suspect that the error comes from computing the checksum, but I am unsure. 
The checksum for IPv6 should be computed automatically from the documentation I saw.
I tried to calculate it myself but was unsuccessful.
