The Bromine Elements stands for Brazilian (BR) Localized Elements
bromine-nit-input is a Material Design field for entering a valid brazilian NIT/PIS/PASEP code.
Example:
<bromine-nit-input></bromine-nit-input>This component is based on gold-zip-input and I didn't clean the code yet, specially for the license parts. If I misused the Polymer or Google name, or didn't credit properly some code, please contact-me.
