Simplify the docs and reduce maintenance burden by just describing the
algorithm by a pseudo-language. Users are encouraged to use libvirt
anyways and projects such as oVirt which do some management of storage

Add a section that outlines usage of tools to handle bitmaps and

With this we can simplify the section about checking bitmap health as we

defined terms.
