Merging changes back to master. Seems to be in a state where the permissions were wrong. Creating a new branch to merge back to master

Putting directory with OHWR as remote repo ( /projects/HEP_Instrumentation/cad/designs/fmc-mtlu/fmc-mtlu/firmware/AIDA_tlu )
into sync with
directory with Github/DavidCussans ( /users/phdgc/tlu-tmp-2018-5-8/work/build/src/firmware_AIDA )

( in with MiniTLU firmware )

Comitting updated schematics for fmc vc . Adding a diagram illustrating coincidence logic. Adding simulation scripts 

test_aida_tlu_trig_counter.py - changed to reflect new address map

Wrote simple firmware to exercise DUT interface pins. Puts out a series of pulses on each pin. See https://elog.phy.bris.ac.uk/elog/AIDA/17 as an example

Wrote a pattern generator function that puts out 0101 pattern then a string of 0. Different number of 01 on different bits

Also, tidying up code and hopefully reducing potential timing-race and meta-stability
issues.

eventFormatter_rtl.vhd

Checking in fixes to triggerInputs - should now provide pulse on trigger_o and trigger_times_o, which had become disconnected

Continuing manual merge of scripted build branch. Removing unnecssary files produced by synthesis, simulation 

Also, a few PCB files updated when I tested cleaned up trunk 
by exporting schematic to pcb.
