Small doc update
new doc macro
Proper getting of read/write functions in loopconfig object.

the loop config, we need to make sure to use the grab the right ones.

Conflicts:

Fix the use of iterator for associative container

The iterator for read and writing associative container are different
(for reading we first need to 'stage' the data), so we need to make
sure to properly initialize them.

the speed of execution as it can be influenced by several different
factors.
