What's New:
Rev. 2.93
 - Fixed bug in updating of timing display window when record size changed.

Rev. 2.90
 - Acquisition mode rebuilt, now has a main menu.  Allows direct access to pause, and
display options like zooming.
 - Pulse generator rebuilt like acquisition, a main menu with same options as acquisition,
and push-button amplitude selection.
 - Dynamic zoom feature added.
 - Added overwrite warning feature - warns you if you are about to do something that
will destroy unsaved data (can be turned off on config menu).
 - Display scale, offset, and gain setting (NOT mode) now stored in parameter files.
 - Fixed bug on labmaster that could cause it to channel skip on multi-channel recordings.

Rev. 2.84
 - Improved stimulus description menuing
 - Added support for gain sampling from amplifiers with serial gain telegraphs
   (Axon GeneClamp 500) and several other amplifiers with analog gain telegraphs.

Rev. 2.7
 - Added real-time display capability for DT282x cards.
 - Added feature to allow outputs to stay at the last level they were at during
   a recording, rather than automatically returning to the defaults.
 - Added auto-filenaming feature.
 - Changed internal triggering for DT282x cards.  No longer need wire from
   binary output (port 1, bit 7) to ext trigger - trigger is generated in
   software.

Rev. 2.6
 - Option added to be able to write file in Clampex 5.2 format.

Rev. 2.5
 - Real-Time display of data during acquisition for Labmaster and Labmaster DMA only
 - Reorganization of menus and parameters.  All items that are stored in
   parameter files are ONLY on the stim/parameters menu.  All other user-
   controllable items are now stored in the config file (all of these items
   are either controlled via the config menu or the pulse generator parameters
   menu).  Note that if you are loading old parameter files, you may need to
   update some items which have now been moved to the config file.  One of these
   items was the D/A attenuation factor.
 - Can now specify useful names and units for A/D (input) and D/A (output)
   channels.  See Config/Inputs or Config/Outputs.
 - Improved support for various amplifiers.  More gain telegraphs directly
   supported.  Also added support for filter telegraphs or for user specified
   filter settings.
 - Gain and Filter telegraphs *should* now be readable with the Data
   Translation DT2821 family of boards.
 - Added amplitude and time axes to main data viewer (about time!).
 - Improved file manager - can now cursor select directories and drives.
 - Added two new parameters to stimulus design.  These allow you to specify
   that a stimulus event will only occur on certain records.
 - Gains are now specified in mV/user units.  NOTE that they used to be
   specified in user units/V.  Make note of this change!!!
