--"A container to specify how to save a core file.
--
--SBSaveCoreOptions includes API's to specify the memory regions and threads to include
--when generating a core file. It extends the existing SaveCoreStyle option.
--
--* eSaveCoreFull will save off all thread and memory regions, ignoring the memory regions and threads in
--the options object.
--
--* eSaveCoreDirtyOnly pages will capture all threads and all rw- memory regions, in addition to the regions specified
--in the options object if they are not already captured.
--
--* eSaveCoreStackOnly will capture all threads, but no memory regions unless specified.
--
--* eSaveCoreCustomOnly Custom defers entirely to the SBSaveCoreOptions object and will only save what is specified. 
--  Picking custom and specifying nothing will result in an error being returned.
--
--Note that currently ELF Core files are not supported.
