Started work on laboratory searches. Most files are changed to reflect the call to search changing to 'laboratorySearch'. Primary changes are in s2_root and s2_search_resource.
Merge branch 'Laboratory_Searches' of github.com:mikemases/S2Mapper

Laboratory searches
corrected the behaviour:
+ laboratorySearch and supportSearch, when 'sent' to the server, produce a request of the following form:
{
"search": {...}
}
instead of using their resource type ( i.e. { "laboratorySearch":{...}} )

+ The resourceType of the resource looked for is injected in the resource processor of the Root. This allows the 'search' resources to be properly processed on the way back
