relatorio: Add support for Python 3

[yangoon, 2013-06-20 15:11:21]

I think it will be best to go through step by step.

1)

In a virtualenv with python3.3 running the tests:

python ./relatorio/relatorio/tests/test_api.py
returns nothing

python ./relatorio/relatorio/tests/test_odt.py 
Traceback (most recent call last):
  File "./relatorio/relatorio/tests/test_odt.py", line 25, in <module>
    from cStringIO import StringIO
ImportError: No module named 'cStringIO'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "./relatorio/relatorio/tests/test_odt.py", line 27, in <module>
    from StringIO import StringIO
ImportError: No module named 'StringIO'

2) missing migration to print as function

mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_odf.py 
  File "relatorio/examples/demo_odf.py", line 13
    print "generating output_basic.odt... ",
                                          ^
SyntaxError: invalid syntax

   
mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_repository.py 
  File "relatorio/examples/demo_repository.py", line 28
    print "generating '%s'..." % filename,
                             ^
SyntaxError: invalid syntax

mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_sheets.ods 
/home/mathiasb/.virtualenvs/venv_33_relatorio/bin/python: can't find '__main__'
module in 'relatorio/examples/demo_sheets.ods'

mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_chart.py 
Traceback (most recent call last):
  File "relatorio/examples/demo_chart.py", line 2, in <module>
    from relatorio import Report
  File
"/home/mathiasb/.virtualenvs/venv_33_relatorio/lib/python3.3/site-packages/relatorio/__init__.py",
line 13, in <module>
    import templates
ImportError: No module named 'templates'

mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_context.py 
  File "relatorio/examples/demo_context.py", line 9
    print "generating output_basic.pdf... ",
                                          ^
SyntaxError: invalid syntax

    
mathiasb@obelix:~/.virtualenvs/venv_33_relatorio$ python
relatorio/examples/demo_sheets.ods 
/home/mathiasb/.virtualenvs/venv_33_relatorio/bin/python: can't find '__main__'
module in 'relatorio/examples/demo_sheets.ods'

3) only just importing relatorio

mathiasb@obelix:~/.virtualenvs$ python
Python 3.3.2+ (default, May 27 2013, 23:57:07) 
[GCC 4.7.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import relatorio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/home/mathiasb/.virtualenvs/venv_33_relatorio/lib/python3.3/site-packages/relatorio/__init__.py",
line 13, in <module>
    import templates
ImportError: No module named 'templates'

You simply did not install the package.

??

mathiasb@obelix:~/.virtualenvs$ pip install relatorio

So don't run the code from archive but the one installed.
