Make it works with Python 3.5

Hi @tracycool, this lib looks awesome.
I could make it works with python 2.7 but not with python 3.5.

There is some issue importing:

python3 cmd.py 
Traceback (most recent call last):
  File "cmd.py", line 1, in <module>
    from easycommandline import program
  File "easycommandline/examples/easycommandline/__init__.py", line 1, in <module>
    from easycommandline import program
ImportError: cannot import name 'program'

I tried to modify __init__.py and easycommandline.py imports headers.
I don't really understand why eval() function is used for at the end of easycommandline.py file.

Do you think it's easy to port this code to Python 3?
Will you do it?
Do there is other python3 lib like this one?
I couldn't found other great ones like this one.
I found that strange that no one ever report that issue.

Thanks.

Anyway, I found an other great lib to manage commands and options which handle Python 3.5:

• commandlines.

I let open the ticket in case someone have same issue.
