[Scip] Creating a Hash Map for SCIPcopy

[Timo Berthold]

Hi Matthias,

you can get access to the block memory pointer by calling SCIPblkmem(scip)
which is defined in scip.h. As an example for passing information forward
and backward between a source SCIP and a target SCIP, see, e.g., the RENS
heuristic.

Best regards,
Timo
