Delphi wrappers for HJCFIT

[raquelalegre]

Some HJCFIT user wants to be able to use the likelihood functionality from Delphi code. We are using Swig for Python and it seems you can also use it for Delphi, see here.

There is also the option to do it from scratch like this: ftp://ftp.freepascal.org/fpc/docs-pdf/CinFreePascal.pdf

It's unlikely that we are able to do this before the end of the eCSE project, but if there is time we could try to make a proof of concept and keep on working on this later on as a separate effort.
