/* This method walks through all of the available configurations (e.g. Debug, Release, Foo) and
* attempts to fetch the values of a couple of properties from the project (CodeAnalysisRuleSet
* and CodeAnalysisRuleSetDirectories). The collected data is put into a data object
* and returned to the caller. The collected data includes the DTE Property object itself, which
* is used later to update the ruleset value.
*
* TODO: consider refactoring. The code seems over-complicated: it finds the "ruleset"
* property for all configurations, then backtracks to find the configuration, then looks
* for the corresponding "ruleset directories" property.
* Note: we are now fetching the "ruleset directories" property from the MSBuild project,
* rather than through the DTE (the previous version of this code that used the DTE fails
* for C# and VB projects that use the new project system).
