> ##Description
> This program aims to provide the support to identify geonames for any 
> unstructured text data in the project NSF polar research. 
> https://github.com/NSF-Polar-Cyberinfrastructure/datavis-hackathon/issues/1
> This project is a content-based geotagging solution, made of a variaty of NLP 
> tools and could be used for any geotagging purposes. 
> ##Workingflow
> 1. Plain text input is passed to geoparser
> 2. Location names are extracted from the text using OpenNLP NER
> 3. Provide two roles: 
>       * The most frequent location name choosed as the best match for the 
> input text
>       * Other extracted locations are treated as alternatives (equal)
> 4. location extracted above, search the best GeoName object and return the 
> resloved objects with fields (name in gazetteer, longitude, latitude)
> ##How to Use
> *Cautions*: This program requires at least 1.2 GB disk space for building 
> Lucene Index
> ```Java
>       function A(stream){
>               Metadata metadata = new Metadata();
>         ParseContext context=new ParseContext();
>         GeoParserConfig config= new GeoParserConfig();
>         config.setGazetterPath(gazetteerPath);
>         config.setNERModelPath(nerPath);
>         context.set(GeoParserConfig.class, config);
>                
>         geoparser.parse(
>                 stream,
>                 new BodyContentHandler(),
>                 metadata,
>                 context);
>    
>        for(String name: metadata.names()){
>          String value=metadata.get(name);
>          System.out.println(name +" " + value);          
>        }
>     }
> ```
> This parser generates useful geographical information to Tika's Metadata 
> Object. 
> Fields for best matched location:
> ```
> Geographic_NAME
> Geographic_LONGTITUDE
> Geographic_LATITUDE
> ```
> Fields for alternatives:
> ```
> Geographic_NAME1
> Geographic_LONGTITUDE1
> Geographic_LATITUDE1
> Geographic_NAME2
> Geographic_LONGTITUDE2
> Geographic_LATITUDE2
> ...
> ```
