Describe the task:

Development of Triangulation methods

The Weighted Centroid Triangulation has already been implemented. It's simple 
and fast, but not very accurate.

Next Task: Implement the Local Signal Strength Gradient method.

This issue was updated by revision r94.

Added Local Signal Strength Gradient triangulation algorithm. Note that this is 
work in progress, the "arrows" calculated still need to be weighted by it's 
signal strength. That's one of the principal reasons why the algorithm is still 
inaccurate.

This issue was updated by revision r95.

Improved Logal Signal Strength Gradient algorithm by weighting each calculated 
"arrow" by the signal strength of the center point.

This issue was updated by revision r129.

Updated the best parameter values for LSSG and Weighted Centroid trilateration. 
Changed the default algorithm back to Weighted Centroid as it proofed to be 
more accurate and way faster.
