; PURPOSE:
;	Clean up heap variables
; CATEGORY:
;	RemoteView package
; CALLING SEQUENCE:
	PRO RemoteView_Destroy_FOV, FOVInfo
; INPUTS:
;	FOVInfo			array; type: structure
;						array of FOVInfo structures
; OUTPUTS:
;	(none>
; INCLUDE:
	@compile_opt.pro			; On error, return to caller
; PROCEDURE:
;	Destroy heap variables associated with FOVInfo.view_elo and FOVInfo.matrix
;	The FOVInfo structure contains three pointers to heap variables.
;	FOVInfo.view_elo always needs to be cleared.
;	FOVInfo.matrix and FOVInfo.matrixb only need to be cleared if they point
;	to an interpolated matrix (see href=RemoteView_Init_FOV=).
; MODIFICATION HISTORY:
;	JULY-2001, Paul Hick (UCSD/CASS)
;	JULY-2002, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
;		Updated to handle pointer to magnetic field.
