Edit MappingPdxSerializer type filter documentation to cover includes and excludes [DATAGEODE-125]

[spring-projects-issues]

John Blum opened DATAGEODE-125 and commented

Provide documentation around using both include and exclude type filters with the o.s.d.g.mapping.MappingPdxSerializer, and using include filters to include a type excluded by an exclude filter.

For example, the MappingPdxSerializer now "excludes" null types, all Java types (i.e. java* packages, e.g. java.*, javax.* and so on), all com.gemstone.gemfire, org.apache.geode and org.springframework types, by default. However, if a user still wanted the MappingPdxSerializer to de/serialize java.scurity.Principal types, for example, then a user only need add a include type filter for the java.security.Principal type or everything in the java.security.* package, etc. The user can be as granular as s/he chooses
