Adding BarBuilder and TimingMapBuilder classes. Expands functionality for
Bar style detectors.

In line with these new classes the VANDLE naming conventions have been
changed to be type "vandle" subtype {small,medium,big}. The left and
right desiginations are handled as tags now. This has served to allow
a quicker and more condensed building of VANDLE bars.

In addition, we have renamed ChanIdentifier -> Identifier to keep in line
with the file name reflecting the class name.

Moving Configurations to optional cfg repository
Adding VANDLE LeRIBSS 2012 sample file
Paring down VANDLE histograms. Adds functionality for medium bars.

We have prepared the VANDLE processor to handle the medium sized bars.
This meant that we had to remove some of the old histograms. Many of these
histograms were either never used, or used only in specific implementations.
These histograms were removed.

The types of bars that are in the analysis is now set in the
DetectorDriver/VandleProcessor node. See the 77cu-test configuration for
the usage.

Adding new DoubleBetaProcessor for the new SiPMT Betas

Retooling VANDLE processor to handle these new double sided betas. We are
currently reading in both sets of maps and then looping separately, with
a lot of repeated code (smelly). This will need to be handled better later.
The Double Betas will supersede the single sided ones (as from LeRIBSS),
since the histograms currently plot into the same spaces. This will be
fixed in a future release.
