twist should be 0 by default.
Merging in Monday's changes
Added a mutex for Sensors. Telemetry should now report temps even if camera is disconnected
Added readFITSHeader function. Currently only reads time values.
Added ntp.conf to configure ntpd, added commands to configure it in install.sh
Adding a copy of the ntpd.service file running in the SAS cans for posterity
Removed the mkdir call from install.sh, adding it to proc instead.
install.sh now just copies the ntp.conf file and enables the service.
Merge pull request #148 from akcramer/master

NTP Configuration
Merge pull request #149 from ehsteve/master

NTP updates and CTL test command
Modified AspectTest to generate CSV
Added Kurt's ir104 code
Removed all references to Mutex in DioDevice.h
Changed indentation in relay code to match existing
Removed references to stdafx.h, removed dscud.h
Modified Makefile to include paths to Diamond Systems drivers
First cut at using IR104 drivers in relays.cpp. Needs to be installed and run on SBC: pre-compiled Diamond Systems library is 32-bit
relays.cpp compiles and runs on SBC, but only flips a single relay
Kurt's code applied only to IR-104 board. Made two new files for the Pearl-MM board, changed DSCUD function calls. Need to see what these actually write/return on the board.
Dumped DIO interface to PMM, modified port and relay functions
