- Added a multiple histogram memory control module. This required a

tiny change in the countable interface which in turn required updating
  of header file includes in a lot of files.
- Some small fixes to TRICS writing as well.

+\subsection{HM control}
+At TRICS (and possibly at other instruments) it it necessary to coordinate the 
+operation of the counter and one to many histogram memories. The
+neutron counter will act as the actual controlling instance and the
+histogram memories will act as slaves. This is implemented in this
+module. 
+
+The modules data structure:
+@d hmcontroldata @{
+	typedef struct {
+			pObjectDescriptor pDes;
+			pICountable pCount;
+			pICountable slaves[MAXSLAVE];
+			void *slaveData[MAXSLAVE];
+                        int nSlaves;
+			float fPreset;
+			CounterMode eMode;
+			} HMcontrol, *pHMcontrol;
+@}
+The fields are:
+\begin{description}
+\item[pDes] The standard SICS object descriptor.
+\item[pCount] The countable interface of this module.
+\item[slaves] The slave counters or histogram memories.
+\item[slaveData] is the data structure for the slave. The first slave
+is always the neutron counter. 
+\item[nSlaves] The number of active slaves.
+\item[fPreset] The counting preset.
+\item[eMode] The counting mode.  
+\end{description}
+
+
+Most of this modules functionality is built into the countable
+interface functions. Just an interface to the interpreter is needed:
+
+@d hmcontrolint @{
+	int MakeHMControl(SConnection *pCon, SicsInterp *pSics, 
+                          void *pData, int argc, char *argv[]);
+	int HMControlAction(SConnection *pCon, SicsInterp *pSics, 
+                          void *pData, int argc, char *argv[]);
