Added functionality

[mykeels]

I understand this was written for a blog article, however it has been really useful and I'd like to add these functionalities:

• added string-compare to support case-insensitive and fuzzy comparisons
• removed redundant Hello.vue
• removed babel stage-2 because .env makes it redundant
• added Usage section in README.md
• used classes instead of inline-styles in component
• added refs to enable access from the global scope
• added limit, placeholder and threshold props
• updated the "main" property in package.json to export the Autocomplete.vue component

Sample Usage:

import VueComplete from 'v-complete'

Vue.use('v-complete', VueComplete)

<v-complete
  :suggestions="[
    { 'name': 'Bangladesh', 'description': 'Bangladesh' },
    { 'name': 'Lagos', 'description': 'Lagos' }
  ]"
  :limit="5"
  :threshold="0.3"
  value="Lagos"
  placeholder="Select a City"></v-complete>
