- Fixed a few problems with hklscan

- Added transfer of zipped data to conman.c, histogram memory software
  in order to support the TRICS status display.
- Upgraded TRICS data file writing.
- First installment of triple axis spectrometer support: initialization of
  data structures and an implementation of the MAD dr(ive) command.

+\subsection{Triple Axis Spectrometer Software}
+A triple axis spectrometer performs complicated scans in Q--energy space.  
+The triple axis spectrometers pose a couple of challenges to the SICS
+software:  \begin{itemize}
+\item The command syntax should be as close as possible to the syntax
+of the ancient tasmad program.
+\item A relatively complicated algorithm is used for computing the
+motor positions and magnet settings. It is a selling point when the
+F77 routine used for this purpose in tasmad can be reused.
+\item A ILL format scan file must be written after each scan in order
+to provide compatability with existing data analysis software.  
+\item Provisions must be made to  execute a batch file at each scan
+point in order to allow for polarisation analysis. 
+\item The user interface of tasmad is largely based on parameters
+which are used to store and manipulate state information. 
+\item There exists a special syntax for assigning variables which
+requires the parameters to be in a special storage order. 
+\end{itemize}
+
+These requirements are implemented in the following way: tasmad
+variables are matched to SICS variables. The scan and drive commands
+are reimplemented in order to allow for both syntax parsing and the
+reuse of the triple axis calculation routines. In order to support the
+strange storage order assignment system the set command is also
+implemented in this modules as it can share code with scan and drive. 
+All the remaining syntax adaptions will be implemented in the
+scripting language.   
+
+
+\subsubsection{Data Structures}
+It would be inconvenient to search all necessary parameters in the
+interpreter anytime a scan or drive command is used. In order to avoid
+this, the parameters are cached in a local data structure which is
+initialized when installing the tas module. 
+
+@d tasdata @{
+typedef struct {
+	pObjectDescriptor pDes;
+        pSicsVariable tasPar[MAXPAR];
+        pCounter counter;
+   }TASdata, *pTASdata;
+@}
+\begin{description}
+\item[pDes] The standard object descriptor required for any SICs
+object. 
+\item[floatPar] An array of pointers to float parameters. 
+The parameters are indexed through defined constants.
+\item[counter] A pointer to the neutron counter.
+\end{description}
+The constants for the parameters are defined in the header file. 
+
+\subsubsection{Exported Functions}
+These are mainly the interpreter inetrface functions:
+@d tasfunc @{
+  int TASFactory(SConnection *pCon, SicsInterp *pSics, void *pData,
+                 int argc, char *argv[]);
+  int TASDrive(SConnection *pCon, SicsInterp *pSics, void *pData,
+                 int argc, char *argv[]);
+  int TASScan(SConnection *pCon, SicsInterp *pSics, void *pData,
+                 int argc, char *argv[]);
+  int TASSet(SConnection *pCon, SicsInterp *pSics, void *pData,
+                 int argc, char *argv[]);
+@}
