Yield

[MJCliffe]

Feature request:

• We'd also like to be able to indicate yield outside of just the free text block. Is likely to be very important information to search on for synthesis optimisation.

Might be connected to #442

Definitely do-able, in the past we have discussed having an extra row in the synthesis information that shows the current sample, with the possibility to add a quantity (mass, volume, % etc) there too.

Related bug/usability question, what should we do to the yield when a starting material is removed or changed. Right now we keep the value (of quantities) and the old reference but this can be confusing. I guess the only ways around this are:

• better UI showing whether something is now inlined and out of sync
• using #deleted to never actually delete things and retain the proper reference to be updated
• constantly update relationships in both directions when nodes change
