FOPWorkEstimates

This Wiki Page attempts to describe the work needed to get FOP's HEAD ready for an initial release, a 0.3 say. It consolidates the layout issues listed on [1] and [2] and attempts to assign a priority and finger in the air estimate to complete/implement. There are plenty of other things required for a full 1.0, but these are listed elsewhere. Aiming for an initial 0.3 release rather than a 1.0 is more practical and hopefully more likely to be acheived. Other items listed on [1] can then be attempted after an initial release has been done.
