Allow ascii output for verification plots
Plot verification data on a map
Added economic value and map/text for Contingency plots
Added Hanssen Kuiper and DMB scores
Various bug fixes

Check that init < 24
modified:   src/Drivers/Comps.cpp

Previously filtering by 'allowLocations' was not done when locations were created from namelists.

Correction in comment
modified:   src/Metrics/Bias.h

* Bug in determining when to use climatological variances as weights
modified:   src/Selectors/Analog.cpp
Documentation of options

* Added VarConf class
Averager class operates on distribution, not ensemble

* Averager works on distribution instead of ensembles. This avoids
  having to create ens from distribution, then deterministic.
* Improve ConfigurationDefault::toString() by forcing the configuration
  to use UncertaintyCombine so that Continuous and Discrete objects are
  visible.
Improve code that automatically detect the available dates in an Input

* Force input schemes that do not have standard data files to specify
  their start and end dates.
* Otherwise poll for available datafiles, and stop when 365 consecutive
  days are empty.
* Fixed a bug in parsing the file format when location Id is used (%L)
Add y-labels for some verification plots
Added CorrectorClimReg
Add spatial elevation gradient in DownscalerNearestElevation

* Compute elevation gradient when creating locations
* Allow weighting of gradient in DownscalerNearestElevation
* Compute gradient in InputNetcdfCf
Add AveragerMean
Safeguard against no obs input defined
Show gradient information in Info driver
Various uninportant fixes
Added new verification plots
Cache the best neighbours in DownscalerNearestElevation
Use the new averagers in default namelists
Allow files to have missing variables

* Previously COMPS aborts if a variable specified in the namelists are
  not found in a NetcdfCf file. Instead set all values to -999.
Recognize attributes in InputNetcdfCf

* Recognize scale_factor, add_offset, and _FillValue attributes when
  reading NetcdfCf datafiles.
