Added the function isFinite(), and replaced the calls to finite() with it.
This was necessary because finite() is not a standard function. Neither can
we use its standard counterpart isfinite(), because it was introduced only
in C99, and therefore it is not supplied by all C++ implementations.

 #!/bin/bash

 for((i=1;i<50;i++))

 do

     echo -n $i ''

     edge_lookup 100 $i

 done
