BHoM Sample Scripts

#### Description:

**BHoM Sample Scripts UI Component**

Ladybug tools has a very useful grasshopper component, which allows for sample grasshopper scripts to be imported directly into the canvas. I think it would be very useful to have a BHoM equivalent functionality , to allow import of sample scripts from each of the dependant toolkits (where relevant).

Functionality would include;
- BHoM UI Canvas object
- Set up of a 'samples' directory
- UI object to reference directory and include file/directory selection UI
- Import of the grasshopper script , directly into the canvas

Consideration may be needed for the set up of a samples folder; the directory architecture, install location and connection to dependant toolkits

I have prototyped a version of this in the associated branch
