Checks to see if the specified point is inside the rectangle.  A point is inside
if it is &ge; the lower extend and &le; the upper extent.

inside = x &ge; x0 AND x &le; x1 AND y &ge; y0 AND y &le; y1

@param a Rectangle.
@param x x-coordinate of point being tested for containment
@param y y-coordinate of point being tested for containment
@return true if inside and false if output
