Test for libraries in SCons
Parameters now are produced for each output location (instead of each obs location). Finders disabled for now.
Added ability to select which obs to use when updating parameters
Change Finder to Location
Implemented parameter regions
Faster build in SCons
Use Region for selecting observations in parameter estimation; Bug in getting momemnts of an ensemble.

Previous commit still used ObsSelector to pick which Obs to use in parameter estimation. Use
Region instead. Currently does not use offset selection from Region.
