Take account of collar weight in weights data file

[HarryHMarshall]

Currently the weight in the weights data file is the total weight entered in the group composition (i.e. the mongoose plus its collar if it has one). When you look back at this data there is no way of knowing which mongoose had a collar on and how heavy it was (and so how much needs taking off).

Would it be possible to either:

• account for the collar weight in the weights data by automatically subtracting the collar weight from any weight that is inputed. or,
• add a field in the weights data for the collar weight to be recorded so it can be subtracted at a later date?

Done now I think. Close?
