SGP/CO2FLX/C1 - Met stand was moved

Ameriflux program (Hank Loescher from Oregon state university) visits the site to 
intercompare his instruments with our 4m flux system.
The met stand was moved by 30 feet and consequently:
1. Soil moisture sensors were disconnected,
2. Soil temperature sensors were disconnected,
3. Soil heat plates were disconnected,
4. The true direction of the anemometer boom was 230 degrees instead of the regular 270 
degrees.

Wind direction should be corrected by users.

• average of two middle soil temperature sensors(mean_t_soil_middle)
• average of two upper soil temperature sensors(mean_t_soil_upper)
• average of four upper soil moisture sensors(mean_m_soil_upper)
• average of four lower soil moisture sensors(mean_m_soil_lower)
• Wind Direction(wdir)
• average of up to four soil heat flux sensors(mean_g_soil)
• average of two lower soil temperature sensors(mean_t_soil_lower)
