In this patch, we mainly streamline the tests on network attributes, by
applying proper line breaks, introducing global constants, and fixing
the accidental introduction of factors for the developer roles.

This tackles some comments in PR #67.

With respect to PR #67, logging statements, line breaks, and
capitalization in sqldf-statements are updated.

To get the very first and the very last activity across all data
sources, i.e., the earliest/latest timestamp of all data sources, for a
ProjectData object, we add a parameter 'outermost' to
'ProjectData$get.data.timestamps' that makes this possible.

Props to @bockthom for his support.

Formerly, we provided three different aggregation levels in the function
'split.data.by.networks': namely, "range", "cumulative", and "project".
We now extend and adapt this to the levels "range", "cumulative",
"all.ranges", "project.cumulative", "project.all.ranges", and
"complete".

The various aggregation levels work as follows:
- range: The project data will be split exactly to the time ranges
         specified by the networks' names.
- cumulative: The project data will be split exactly to the time ranges
         specified by the networks' names, but in a cumulative manner.
- all.ranges"}: The project data will be split exactly to the time range
         specified by the start of the first network and end of the last
         network. All data instances will contain the same data.
- project.cumulative: The same splitting as for \code{"cumulative"}, but
         all data will start at the beginning of the project data and
         *not* at the beginning of the first network.
- project.all.ranges: The same splitting as for \code{"all.ranges"}, but
         all data will start at the beginning of the project data and
         *not* at the beginning of the first network. All data instances
         will contain the same data.
- complete: The same splitting as for \code{"all.ranges"}, but all data
         will start at the beginning of the project data and end at the
         end of the project data. All data instances will contain the
         same data.

In this patch, we properly extend all functions and tests.

The function 'add.vertex.attribute.author.role' now adds author-
classification attributes based on classification results. The function
'add.vertex.attribute.author.role.function' is now the one using a
classification function as a parameter.

For this to work, we add the range identifier as a parameter to the
anonymous calculation functions for adding the vertex attributes.

For better modularity, the function 'get.commit.data' is moved to the
data module, right where it obviously belongs.

This code originates from @flx5's PR on vertex attributes (#67).

Signed-off-by: Claus Hunsen <[email protected]>

This patch introduces only some minor fixes and inprovements to the
documentation for the changes in PR #93.

The most important change is the renaming of the function
'add.vertex.attribute.commit.count' to
'add.vertex.attribute.commit.count.helper', mainly for unambiguity and
consistency reasons.

Props to @bockthom for being that precise.
