NAME
	  DtFaceCount -	Determines the number of faces in a given list
	  of vertex indicies.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtFaceCount( int	indexCnt, long *indices	)


     DESCRIPTION
	  DtFaceCount()	returns	the number of faces or lines given the
	  size of the index list, via the indexCnt parameter, and the
	  index	list, via the pointer to the indices parameter.	 For
	  example, if

	       1 2 3 -1	4 5 6 -1

	  is stored in the indices parameter, this function should be
	  executed as follows:

	       faceCnt = DtFaceCount( 8, indices );

	  The resulting	value of faceCnt is 2.
