C++ library for developing new DHS programs

The dcsmsg project is a C++ library for handling the DCS message protocol for new DHS development. This project allows developers to build support for new hardware rapidly. There are several example DHS projects that use this new library:

1. Adac5500DHS (A/D card support for the adac5500 card).

2. Dsa2000DHS (Support for the DSA2000 fluorescence detector.)

3. epicsdhs (Reads PV's and can wait for PV's to become a certain state.)

4. impdhs (Allows access of an impersonation server via a DHS operation command.)
