Fixed for inconsistencies in (l,p) <-> (x,y) mappings between libs.

jLinda semantics references line/azimuth coordinates to first (-> x)
coordinate, and second coordinate to to pixel/range axis (-> y) -
logic adopted from geodesy. While NEST-core references range to x-,
and azimuth to y-coordinate direction.
Fixed bug in getting slave imagette for fine-offset-computations.
Clean-up of code for defining a grid of correlation-windows.
Refactored sout to use logger in CoarseFineCoregOp.

Hardcoded logger output level to WARN.
Correct handling of bands, to allow Resampling work in graph.
Fix for computation rms of CPM.

Clean-up initialization math, and refactored from Trove's
TDoubleArrayList to primitives double[].
Fix for logging level of Coarse & Fine coregistration.

For proper logger configuration had to move logger setLevel from
initialize to the class constructor. Otherwise it fails through to
INFO level.
Getters of mutable fields/classes creating new objects. [Core]

  Note: An interim resolution of issues with mutable fields of core
  classes.
Fixed check-box for DEM offset refinement in Resampling UI. [Coreg]
Reworked math for DEM based coreg offset refinement. [Coreg]
Fixed DEM management for geometry based offset refinement. [Coreg]
