BUG: Symmetric bounding box in training and detection phases of BCD
ENH: perform the local search of BCD in Freq domain

The "FindCandidatePoints" method is reimplemented to do the local search
in freqency domain.
First, based on the search bounding box, an ROI image is created from
the input MSP volume. Also, the landmark template intensities are
arranged inside an moving template image.
Then, for both fixed and moving images, corresponding maskes are
created, and the "MaskedFFTNormalizedCorrelationImageFilter" is used to
the final optimum match.

BCD is run faster now:
The average of previous run time: 3m40
The average of current run time: 1m40

That shows more than 2x speed increase.
ENH: Add version number to input template and LLS model files
ENH: add the new template files to ReferenceAtlas/20140916_BCD directory

The current LLS model file (LLSModel_50Lmks.h5) and template model file
(T1_50Lmks.mdl) are updated.
New model files have version ID (v1.0) embeded in them.
ENH: Update the current address of BCD model files to the new one
ENH: Remove irrelevent parameters from BRAINSFit

The following parameters are cleaned from the code and xml file:

useCachingOfBSplineWeightsMode
metricSeed
forceMINumberOfThreads
permitParameterVariation
useExplicitPDFDerivativesMode
WIP: Needs more work on SEM tools. DO NOT SUBMIT THIS.
COMP: ITK Components needed for build.
WIP: Removed BRAINSSurface building.
ENH: Updated SEMTools to new command line usage.
BUG: Filenames needed to change from hdf5 to h5 extension in autoworkup.
ENH: Integration of ANTs Multimodal Registration into BRAINSFitHelper

While doing SyN registration, you can use SetFixedVolume2() and
SetMovingVolume2() in BRAINSFitHelper to run a multi modal image
registration.
In BRAINSFit, SyN registration had been hard coded to run one stage of
registration using ANTs.
Now this stage can have one or two metrics (for multi-modality
registration). All the parameters of the second metric is the same as
the first metric except for the fixed and moving volumes.
