innerplot: Plot inner model

Plot the inner (structural) model fora path matrix. Adapted from plspm package by Gaston Sanchez.

`x`	Either a matrix defining an inner model or an object of class `"plspm"`.
`colpos`	Color of arrows for positive path coefficients.
`colneg`	Color of arrows for negative path coefficients.
`box.prop`	Length/width ratio of ellipses.
`box.size`	Size of ellipses.
`box.cex`	Relative size of text in ellipses.
`box.col`	fill color of ellipses,
`lcol`	border color of ellipses.
`box.lwd`	line width of the box.
`txt.col`	color of text in ellipses.
`shadow.size`	Relative size of shadow of label box.
`curve`	arrow curvature.
`lwd`	line width of arrow.
`arr.pos`	Relative position of arrowheads on arrows.
`arr.width`	arrow width.
`arr.lwd`	line width of arrow, connecting two different points, (one value, or a matrix with same dimensions as `x`).
`cex.txt`	Relative size of text on arrows.
`show.values`	should values be shown when `x` is a matrix.
`...`	Further arguments passed on to `plotmat`.
