*   CONDAT - Common block for the contour routines.
*   Variables : XDONE, YDONE: Keeps track of grid crossings
*               TRANS       : Yes/no conformal mapping
*               CLAB        : Yes/no labeling of contours
*               GRID        : Array of contour heights on the grid
*               EPSTRA      : Epsilon for tracking a contour
*               EPSGRA      : Epsilon for computing gradients
*               D(XY)GRA    : Step size for computing gradients
*               C(XY)M(INAX): Area for which the contours are made
*               STINIT      :
*               DNTHR       : Grid crossing tolerance
*               NFC         : Number of funtion calls used for contours
