explore the idea of adding a reset function.

[wilmoore]

I haven't thought through the API much yet, but off the top of my head, my ideas would be:

.reset API

envc.reset();
envc.reset(options);

options API

envc({ reset: true })

approximate implementation

for (var key in parsed) delete process.env[key];

[wilmoore]

I've just come up with a use-case that I didn't think of originally. If a variable (i.e. process.env.SECRET = 42) is set before envc is called, where .env contains the following:

SECRET=99

I would expect that calling .reset results in process.env.SECRET = 42.

Would be nice if you could selectively reset as well....

envc.reset('SECRET');
