Detailed Description

Store a shared chunk of binary info with reference count to avoid copying.

Implements mDirty flag to mark for updates. Implements mLoaded flag to use when subclassing or in a context where want to differentiate between not being loaded and having loaded a zero-size BLOB. Use as a pointer member, copying the pointer and calling incRefs or decRefs each time you copy the pointer or destruct the oofSharedBLOB.

Todo:

write oofSharedCOWBLOB providing quick duplication for COW. (Copy-On-Write).
