(i.e. stuff that's stored in our datafiles). Keep those checks for user-supplied values
(i.e. coordinates coming from files during preprocessing, or coordinates supplied by users
during requests)
adjust to generalFindMaximum function
moved parallel detection to ratio/absolute based regression testing
considerably improved detection quality using normalised regression lines
only follow initial direction/narrow turns for parallel detection
StaticRTree now uses projected coordinates internally. That means we can
use a euclidean distance measure (squared distance) for sorting the
query queue.
