More firmware development:

Took copies of firmware/hdl/i2c_master_* to avoid having to pull in.

Wrote some test-benches for data mux code:
dummyMarocADC_behavioural.vhd
marocTimeStampMuxArray_tb.vhd
marocTimeStampMux_tb.vhd
marocTriggerTimeStampArray_tb.vhd
marocTriggerTimeStamp_tb.vhd

Added pick-and-place information to BoM

marocInterface_rtl.vhd  - Added external trigger from GPIO header as well as from DIN41612 connectors

marocTriggerGenerator_rtl.vhd - added attributes to prevent synchronization steps being optimized to a shift register

- MarocConfiguration.py  - passes configuration file name to MarocSC object and reads from configuration file.

- MarocHistograms.py - replaced print statements with logger.info / logger.debug

- MarocSC.py - debugged so can now read flags, parameters and register values from configuration file.

- takeMarocData.py - added command line switch to set configuration file name

MarocConfiguration - class that writes to registers in FPGA , including register that controls interface to MAROC slow control. Reads data to write to slow control from CSV file.

takeMarocData.py - passes number of events to readout thread. Passes file name to recording thread. Waits for threads to finish before exiting

MarocRecording.py - eventually sorted out how to record to a ROOT file. Inefficient at the moment. 

MarocSC.py - started to add ability to store register values in CSV file as well as contents of MAROC SC registers.

MarocHistogrammingThread.py,MarocReadoutThread.py,MarocRecordingThread.py,MarocUnpackingThread.py - when readout thread reaches event limit it passes a "special" event along processing pipeline that causes threads to exit.

MarocRunControlThread.py - beginnings of a run-control thread. Not used at the moment.

takeMarocData - multi-threaded top level script to take data.

MarocReadoutThread , MarocHistogrammingThread , MarocRecordingThread - classes that inherit from Threading class

Some documentation changes

Changed Slow control shift register to have optional reset before shifting data.
( Still at least one bug - doesn't store data shifted out of MAROC correctly )

Added register stages to risingEdgeDetect

Edited pc049a_top.vhd in order to only build the IPBus ( not the White Rabbit ) cores by default. Reduces power dissipation and keeps chip cooler.

* Took pictures of assembled boards.

* Exported netlist from Circuit schematic.

* Changed clocks to be 31.25MHz IPBus clock.

* General tidying. Unfortunately, latest design doesn't respond to "ping"....
