Add Nested properties to ES mapping of outbreak.info/resources

[flaneuse]

Due to how ES stores objects, a query of q=firstName:Marco AND lastName:Zhou on

author:[
{firstName: Jerry, lastName: Zhou},
{firstName: Marco, lastName: Cano}
]

would inappropriately return the record containing that author, even though there’s no author “Marco Zhou.”

Enable nested data storage and query syntax as well as facetting on nested objects. Will require parsing of query string to interpret into ES query object, etc. For an example, see implementation in CViSB of ELISA nested queries.
