Fixed areaCell and u,v rotation for wrf mesh. Plotted fields
(u,v,theta,vort) all look consistent now.
Tiny modifications to other files.
For correspondences, now read the basinSimilarityMetrics for all basins
at iTime0 and iTime1. Before, we'd read each site0-corrSites and
site1-corrSites
Adding optional timers to driver
Better timers
Nearest neighbor search for finding the closest cell to advected point
for wrf cases. The NN search in the WRF code just uses the mesh object
interface and so could be plopped into helpers as common code.
Some bug fixes for reading basinSimilarityMetrics too.
Track file after changes matches (empty diff) the track file before
changes. Yay!
Some comments on basinSimilarity for correspondence. This could really
use some more analysis/justification.

Consider writing the tracks files by time (to netcdf?) instead of following a basin
to reduce I/O costs from loading the basinMetrics information.
