The Line Parameters settings allow the user to view and modify settings specific to collecting
data as individual lines, namely, the starting position of the line and line direction.

The Start Position is the position value at the very beginning of a line.  This will usually be set to
zero (0.0).  However, if the user wants a data file to start at a position other than zero, this value
can be edited.

The Line Direction setting specifies which direction that line will be collected, either Forward or
Reverse.  Data are usually collected in a forward direction.

If data are collected in the Forward direction the position stepsize is positive, that is, the position
value of each data collection point increments positively.  For example, for a Noggin 250 system,
if the Start Position is 10.0 and the Line Direction is Forward, the positions on the line will
increment 10.00, 10.05, 10.10, 10.15 ….

If data are collected in the Reverse direction the position stepsize is negative, that is, the position
value of each data collection point increments negatively.  For example, for a Noggin 250 system,
if the Start Position is 10.0 and the Line Direction is Reverse, the positions on the line will
decrement 10.00, 9.95, 9.90, 9.85 ….
