; PROJECT:
;           Solar-B EIS
;
; NAME:
;           EIS_PLOT_cpt
;
; PURPOSE:
;           Plots any of given resource item on the resource row
;
; CATEGORY:
;           Planning, Science
;
; EXPLANATION:
;           This routine plots any of the resource items on the science
;           plan display. Currently, DSN contact times, commanding times
;           (throughput RCR), and delayed commanding times
;           (payload_reserved) should be plotted on the same row; Other
;           station events should be plotted on the other row.
;
; SYNTAX:
;           plot_resource, resource, startdis, row
;
; INPUTS:
;           RESOURCE -  Array of {eis_timeline_graphics_resource} structures
;                       that has at least the following tags:
;               RES_NAME   - Resource type (name of resource item)
;               START_TIME - The beginning times of the resource item, in TAI
;               stop_time   - The end times of the resource item, in TAI
;
;           STARTDIS - Start time of the display, in any CDS time format
; KEYWORDS:
;           ROW       - row number in which the item is plotted (default: 0)
;
; RESTRICTIONS:
;           PLOT_FRAME must be called first.
;
; HISTORY:
;           V0 August 2005 - John Rainnie, RAL
;           Based on "/ssw/soho/gen/idl/science/plot_resource.pro"
;           retained backbone of procedure but changed resouse names etc for EIS
;           choice of row and subrow, now depends on resource type
;           V1 26 July 2006 John Rainnie
