Refining class refactor

some relabeling. Moved where buffer was added to. Removed length checks
for prompt detection and used buffer instead of data. changed callback
function names and added the end even message to sshObj. Changed main
public functions so it could be run as an instance of the class or as
the static method on the class.
Update README.md

Added requirements and example
update SSH2Shell

added response variable for command response text. Removed incorrect
object path for server in sshObj. Added the connected message.
Fixed documentation and extended readme. Added prep for npm package publishing with folder structure and package.json changes. Added prepublish hook
Fixed readme to use git install and not npm until tested and published
Rename SSH2Shell.coffee to ssh2shell.coffee

Tested code and updated example in readme
