Potential translation of LKMM docs into ReST

Hello!

There is interest [1] to get the memory model documentation into the 
built docs. Akira pointed out that this was discussed in the past [2].

A couple of years have gone by, so I was wondering whether the decision
to keep plain text documentation still applies. 

There is an "easy" way [3] to get the plain text documentation into the
built docs, but I would be happy to work in a conversion into ReST if
that's what you want :)

Ccing people involved in [2]

Thanks!
