[Discuss OpenCPI] OCPI Assembly Selection

I believe I am experiencing a pitfall that Adam P. described during training months ago. I'm not sure if I'm reporting a problem or reporting incompetence, but a novice user likely experience this and hours are spent chasing it down. Perhaps there needs to be some improvement (ocpidev; the gui) to require the intended assembly be specified when more than one is found can hook up. And grepping the LOG_LEVEL=8 output is a hard sell. Either that or some super-touch tool to cause all affected assemblies to be rebuilt when a worker is modified (imagine the time that would take).
When running an application ACI if I specify:
Then I get the first assembly that hooks up. I did not know that the search path would include assemblies built for unit testing (but it makes sense). The situation is this:
1. Created a component/worker called transmitter/phy_tx_802dot11g.hdl and a unit tester transmitter/phy_tx_802dot11g.test. The test drives the transmitter with one data file and generates one output file of iqsamples.
2. To test in more real scenario we created an application "phy_tx_802dot11g_app" and an assembly "phy_tx_802dot11g_assy" with only the phy_tx_802dot11g.hdl" worker in it. This app sends multiple data frames and generates multiple bursts to a sample file.
3. To test further we want to build the "phy_tx_802dot11g_assy" for both the base container and for the zed+fmcomms3 container. (see thread with Jim K.)
Had all three above working and then made a modification to the transmitter worker. To test step 2 again I cleaned the phy_tx_802dot11g_assy and rebuilt the worker, then the assembly, and ran the app. Nothing changed. So running the app with OCPI_LOG_LEVEL=8, I see:
OCPI( 8:516.0936): Successfully loaded bitstream file: "/home/pbmiller/SS_SDR/Frameworks/ocpi.core/exports/imports/ocpi.wifiproject/components/transmitter/phy_tx_802dot11g.test/gen/assemblies/phy_tx_802dot11g_0/container-phy_tx_802dot11g_0_xsim_base/target-xsim/phy_tx_802dot11g_0_xsim_base.tar.gz" for simulation
So the application is choosing the assembly from the unit tester rather than the intended one because the OCPI_LIBRARY_PATH was not specific enough. Doing the following fixes the problem:
