Convert a polygon into a planar straight line graph
npm install poly-to-pslgpoly-to-pslg
============
Converts a polygon into a planar straight line graph.
``javascript
var poly2pslg = require('poly-to-pslg')
var polygon = [
[[-2, 2], [2, 2], [2, -2], [-2,-2]],
[[-1, 1], [1, 1], [1, -1], [-1,-1]]
]
var pslg = poly2pslg(polygon)
console.log(pslg)

#### Output
`javascript`

#### var graph = require('poly-to-pslg')(loops[, options])
Converts a polygon into a planar straight line graph.
* loops is an array of loops determining the vertices of the polygon. If only one loop is specified, this is inferred automatically.options
* is an object storing some optional parametersoptions.clean
+ if this flag is set to true, then clean up the resulting graph using clean-pslg. (Default true)options.nested
+ if this flag is set to true, then assume the polygon is an array of loops. If false, then suppose that the polygon is just one array.
Returns An object with two properties
* points are the vertex coordinate of the pslgedges` are the edges of the pslg
*
