Jiayu Shen updated CARBONDATA-4051:
-----------------------------------
    Description:
This is requirement from SEQ，related algorithms is provided by group Discovery.

1 replace geohash encoded algorithm, and reduce required properties of CREATE TABLE. For example,
{code:java}
CREATE TABLE geoTable(
 timevalue BIGINT,
 longitude LONG,
 latitude LONG) COMMENT "This is a GeoTable"
 STORED AS carbondata
 TBLPROPERTIES ($customProperties 'SPATIAL_INDEX'='mygeohash',
 'SPATIAL_INDEX.mygeohash.type'='geohash',
 'SPATIAL_INDEX.mygeohash.sourcecolumns'='longitude, latitude',
 'SPATIAL_INDEX.mygeohash.originLatitude'='39.832277',
 'SPATIAL_INDEX.mygeohash.gridSize'='50',
 'SPATIAL_INDEX.mygeohash.conversionRatio'='1000000') add some geo spatial UDFs,{code}
2 Add some geo UDFs

query filter UDFs

*InPolygonList (List<String> polygonList, OperationType opType)*

***InPolyline (List<String> polylineList, Float bufferInMeter)***

***InPolygonRangeList (List<Long []> RangeList)***

geo util UDFs

***GeoIdToGridXy(Long geoId) :* *Pair<Integer, Integer>***

*LatLngToGeoId(**Long* *latitude, **Long* *longitude) : Long*

***GeoIdToLatLng(Long geoId) : Pair<Double, Double>***

***ToUpperLayerGeoId(Long geoId) : Long***

***ToRangeList (String polygon) : List<Long []>***

3 Currently GeoID is a column created internally for spatial tables, this PR will support GeoID to be customized during LOAD/INSERT INTO
