Issue #1 - Support streams.

Updated per comment.

Also, refactored the tests and index to allow for more readability.

Further reviewing the code...it seems like there are too many paths for the plugin. Ideally there should be a single purpose; i.e. stream csvtojson module using gulp. The current plugin is streaming, but also will create a js file depending on options. The creation of a JS file could(should) be done in a different plugin. Here is the gulp plugin guidelines which provides a little more detail: Gulp Plugin Guidelines

I have opened up another issue(#3) to discuss further.

Here is what currently exists:

var gulp = require('gulp');
var csvtojson = require('gulp-csvtojson');

gulp.task('default', function () {
    return gulp.src('src/file.csv')
        .pipe(csvtojson())
        .pipe(gulp.dest('dist'));
});

I think this should be:

var gulp = require('gulp');
var csvtojson = require('gulp-csvtojson');
var insert = require('gulp-insert'); //module to insert into streamed data

gulp.task('default', function () {
    return gulp.src('src/file.csv')
        .pipe(csvtojson())
        .pipe(insert.prepend('var anyVariable = '))
        .pipe(insert.append(';'))
        .pipe(gulp.dest('dist'));
});

+1 for separating fixtures from cases, however, obvious code duplication between buffers and streams directory which also produces problematic code twice.

Anyway, I suggest for this PR, let's just focus on this stream support, let's merge the PR after the two issues I just raise has been resolved. Then we can continue enhance with less code duplication later.

Yes agree on some duplication...and we can review that. I think if the streams are pushed in. Maybe work on #3 , and remove tests/duplication from there.

Let me know if anything else.
