 a javascript [membrane](https://tvcutsem.github.io/membranes) implementation.
 This implementation is intended to provide *secure* isolation between any number of membrane spaces.
 This implementation intends to support all types of objects including functions, classes, etc.
 By default, all membrane spaces have a "transparent distortion", meaning all operations are forwarded to the original graph.
 In order for this membrane to be useful you will need to provide a distortion implementation.
