This code reads the file Data/out. This file should be in one of two 
formats. The first line should contain an integer, either 999 or 998

If it is 999 then we do a slalom search on a single triangle. The file 
should be in the format
-------------
999
x
y
DEPTH
-------------
Where x,y are doubles/floats, and DEPTH is a positive integer

If the first line is 998, the next line should be an integer 
representing the number of triangles to search with. 
Then the next lines give the x and y values. The last line should 
contain the integer DEPTH. For example
-------
998
3
x1
y1
x2
y2
x3
y3
DEPTH
---------
