Draw a capacitor

capacitor(x0, y0, x1, y1,
          points=FALSE,
          length=0.01, width=length*5,  
          label, pos,
          col=par('col'), lwd=par('lwd'), cex=par('cex'))

`x0,y0`	starting coordinate of element
`x1,y1`	ending coordinate of element
`points`	booline indicating whether to draw dots at the ends of the wire
`length`	distance between capactor plates
`width`	length of plates
`label`	optional string placed near component (see `pos`)
`pos`	optional position of `label`, as for `par(pos)`; defaults to 1 if `horizontal=TRUE`, or 2 otherwise.
`col`	colour
`lwd`	line width
`cex`	size of points (ignored unless `points` is `TRUE`)

The coordinate system has both x and y ranging from 0 to 1.

Vector containing x0, y0, x1, y1.
