Improved headings in README.md file

Normally heading level 1 is reserved for the document's title, every
heading following is lower than the title heading (H1). I went ahead
and set the README's title to H1 and every following section to it's
respecting heading level. Also the title of the document was using the
"========" bar to set it as H1 while the rest of the headings were
using the "##" prefix to set the heading to H2,H3. I edited the
title's heading so it will be uniform with the rest of the document.
Added bash formatting to usage example.

Added the 'bash' keyword to the example code block under the Usage
heading to improve readability.

Made a mistake in my last revert.
Removed the bash formatting to README. I made a mistake in adding it.
Removed the "I" pronoun at the end of the README.

I took out the "I" pronoun from the end of the README where the CVS is
explained. I rewrote the sentences without the use of pronouns.
Additional edits to improve general readability.

I removed all pronouns, "you and I", from the README file and rewrote
the edits so it reads correctly. I also added bash formatting for
command examples.
Fixed an error in the 'apt-get' command example.
