Stale README.me
This seams wrong now:
"Clone this IOC with git clone --recurse-submodules https://gitlab.esss.lu.se/javiercereijogarcia/e3ioc-ecmclebtiris.git
."
... EthercatMC
EthercatMC is now called ethercatmc
But I think that ECMC-users do not use it anymore since a long time
Can we just remove the historic stuff ?
