LOG(NAME,DATA,TYPE,LEVEL) ;Log to MHV application log
 ;
 ;  Input:
 ;    NAME - Name to identify log entry
 ;    DATA - Value,Tree, or Name of structure to put in log
 ;    TYPE - Type of log entry
 ;              S:Set Single Value
 ;              M:Merge Tree 
 ;              I:Indirect Merge @
 ;   LEVEL - Level of log entry - ERROR,TRACE,NAMED,DEBUG
 ;
 ;  Output:
 ;    Adds entry to log
 ;
 ; ^XTMP("MHV7LOG",0) - Head of log file
 ; ^XTMP("MHV7LOG",1) - if set indicates that logging is on
 ; ^XTMP("MHV7LOG",1,"LEVEL") - logging level
 ; ^XTMP("MHV7LOG",1,"LEVEL",LEVEL) = rank
 ; ^XTMP("MHV7LOG",1,"NAMES",) - names to log caret delimited string
 ; ^XTMP("MHV7LOG",1,"NAMES",NAME) - name to log
 ; ^XTMP("MHV7LOG",2) - contains the log
 ; ^XTMP("MHV7LOG",2,negated FM timestamp,$J,counter,NAME) - log entry
 ;
 ; ^TMP("MHV7LOG",$J) - Session current log entry (DTM)
