better ping tool

 prettyping is a simple tool written in Shell to
 show latency between the sending and the destination
 hosts.
 .
 It is a wrapper around the standard ping tool
 with the objective of making the output prettier,
 more colorful, more compact, and easier to read.
 .
 prettyping runs the standard ping in the background
 and parses its output, showing the ping responses
 in a graphical way at the terminal
 (by using colors and Unicode characters).
