[Coin-standards] Revised MPS format

Hi,

I participated in the Maimi meeting and thought one of the ideas was to 
fix the MPS format and create an MPS2002 format, so there was an MPS format 
that every vendor accept and interpretated the same way. 

Is this idea still on?

In my opinion I think the MPS format should be revised so:

1. Allow for the names that are longer than 8 chars.

2. Allow specification numbers with higher precision than 12 figures.

3. Make possible to sepecify all MIPs using bounds section only
and not the "strange" MARKERs.

4. Possibly include information about the objective sense.

5. Possibly include specification of a Q term in the objective.

6. Remove different ambiguities.

I think most vendors deal with the issues but not in the same way. I think it would be nice
agree upon one solution. 

Thanks for your attention.

Erling
