Description

Google's Libphonenumber can provide us with comprehensive support for modeling Phone number metadata properly in Tika.
During the development of this patch I realized two things, namely

• This is not a parser as such as Phone numbers are not mapped to any particular Mimetype
• In addition, there can be many phone numbers per document, so this is most likely a Content Handler of sorts
• Tika's Metadata support is currently too restrictive to allow us to persist many complex objects e.g. String, Object. We need to expand Meatdata support over and above String, String[].
