This tries to strike a balance between giving a useful high level
flow without injecting too much complex detail in each diagram.
For the more complicated resize diagram, I have used labels to
try and make clear which conductor task is performing an action.
For the less complicated confirm and revert diagrams, I add a
separator to show where the conductor task is orchestrating the
calls and provide a bit more detail into what each task is doing
since the calls to computes are minimal in those cases.
