Enable Plume Height and Wind Measurement Dialog to read from 2 eval logs

[dlnorgaard]

Changes were made to address issue #8 in some form, but this did not automatically fix the Plume Height and Wind Measurement Dialog (currently disabled). They are expecting one evaluation log file with both channels, master and slave, in it. The software produces one evaluation log for each channel (i.e. 2). The dialog need to be modified to allow both eval logs to be specified and to process data from.

May need to resolve #89 first.

Mattias completed this but we do not have good data to test the feature with.

Wind Speed Measurement dialog

Plume Height Measurement dialog

Appears to be working, although without knowing expected results and proper input for rest can't confirm the calculations. Christoph has some published info on plume-height calculations using Matlab code he wrote and wind speed from meterological model that he will provide to compare against.

Attaching data from Kilauea with two evaluation logs.
The coordinates for Fissure 8 (active at the time) are:
Lat 19.46137
Lon -154.909135
Angle of separation: 20 degrees
Christoph as wind direction of 59, 55 and 51 for the three traverses on that day. He also got a plume height of about 1100m above the instrument (average for the day).

The wind direction calculated for the 1414 data seems in the ball park but plume height is 0. The wind dir for 1514 seems far off at 285 degrees. Plume height is also 0 here.

This data shows plume height (though quite high). After talking to Christoph, it was determined that we need to be able to select out the part of measurement that is approximately a straight line. If the car is making turns during the measurements, the beams will be going all over the place. In above, the first five minutes is going straight south.

Similarly for wind speed, user needs to be able to select part of the measurement where the vehicle is stationary and the telescopes are aligned with the plume axis.
