Quickstart Hello World

[maphew]

For readme quickstart: a simple recipe that demonstrates the module has been installed correctly and is available for use.

Example not yet working code:

#a-last-hello.py
from ast_token_tools import leoAst as last
print(last.hello())

Out:

Hello %USERNAME%!
     -- from the AST Token & Tools library

nb: I'm using 'last' as an example because it's my personal favourite for the lib/tool's short name, but that's just a placeholder for whatever Edward decides to use officially.
