// serialization of hierarchical object/array/int/str to a flat object and back
// 
// useful to store an object in compressed column store
// so it will be compressed by type and not as blob.
// the resulting object values and keys can be escaped and converted to a sql query

//example:
// var xx=['test',{data:[1,2,"asd"]}]
// result=flat(xx)
