compressArray

["Kalantari Babak" <BABAK.KALANTARI@psi.ch>]

For the synchronous data collection of SwissFEL (and its test facility)
we make intensive use of "compress" record to locally buffer the
acquired data in high rate at each IOC. 

In addition to single valued PVs (scalars) we need to buffer waveforms
as well. This is especially interesting for buffering images and LLRF
data. Before going for any development, I would like to know if anybody
has worked on something which behaves like "compress" record (at least
for buffering) but for waveforms (any custom record types, soft device
supports, etc). 

Any idea is welcome.
