These functions and methods were originally based on the XML output.
Consequently, those variable names were also preserved. All "<name>_xml"
variables are now named "<name>_json" instead.
With this change, gitinspector once again functions in conjunction with
egg installations. Also removed all forceful absolute imports, as these
really aren't needed.
This prepares the source code for the changes discussed in issue #24.
Note that this is just a quick restructuring in order to see the resulting
classes and separation. More work will be done to make it more elegant
and with less dependencies between modules.
