various Improvements

[tripodsan]

sorry for somewhat large PR, but I tried to keep the various changes in individual commits.

what I did:

• added the configuration options to the README
• move the example usage to a example directory
• create proper mocha unit tests that build and test the output
• set proper directories during compilation to allow correct template resolution
• added option to exclude runtime during compilation
• added option to specify runtime variable names
• added option to specify module import generator

Awesome, thanks a lot!

A few notes:

• I would prefer to ditch fs-extra and use fs.mkdir and rimraf instead. This would slightly reduce the dev dependency footprint and we could easily replace rimraf with recursive fs.rmdir at some point (available in Node 10.12+).
• It would be great if the options in the README would link to the corresponding test.

Would you be willing to change this or should we rather merge and I update it myself? I'm planning on adding ESLint after merging this anyway, since we are starting to have enough code to warrant this, so it would be fine to take care of these minor changes as well.

@backflip I think that fs-extras is superior as it it just a think wrapper around fs and adds proper promise support.. you could also use fs.promise instead. I don't mind requiring node 10.12+ for the tests.

please go ahead and adjust the code as you whish...thanks for all your work!

Currently on my phone, but I’ll publish it on npm in the evening.
