The Outputable class is now the base class of all the classes that want to
output formatted text. This is more object oriented and cleaner solution
compared to the previous implementation.
Changed from using the deprecated functions in the os module to using the
new ones in the subprocess module. All string reading now also uses the

Filtering can be specified using an arbitrary number of -x (or --exclude)
parameters. The filtering works in a similar fashion to an inverted grep,
meaning that matched file names will be excluded from the generated
statistics.
To accommodate this modification, the changing of working directory (when
a repository is specified) has been moved from the system module to the
main gitinspector module. This enables us to change directory in one go
when gitinspector starts, thus removing the need for the previous system
module.
It should now be able to handle multi-line comments that are only on one line.
Furthermore, it should also handle multi-line comments from languages such as
python (where the identifiers for comment begining/end are identical).
The metrics module currently only includes a very simple ELOC (estimated lines
of code) metric, but will be expanded eventually with some other metrics.
