static void checkConnectedTo ( BOARD aBoard,

static

Function checkConnectedTo returns if aTracksInNet contains a copper pathway to aGoal when starting with aFirstTrack.

aFirstTrack should have one end situated on aStart, and the traversal testing begins from the other end of aFirstTrack.

The function throws an exception instead of returning bool so that detailed information can be provided about a possible failure in the track layout.

Exceptions
IO_ERROR- if points are not connected, with text saying why.
