Class MemoryFilter

MemoryFilter is a memory buffer that can be used as a source or a sink Filter in the Filter pipeline. When a MemoryFilter is the source, other filters can read data stored in memory; When MemoryFilter is a sink, other filters generate data which is then pushed in a memory buffer owned by MemoryFilter (MemoryFilter makes sure that there is enough space to accomodate all data).
