Capture and give back to users any error messages

[sckott]

either client or server errors, and give back in meta slot

e..g, GBIF gives an error of Error: Points of LinearRing do not form a closed linestring with:

occ_search(scientificName= 'Anopheles arabiensis', 
    geometry =  'POLYGON((42.0 -26.0, 52.0 -26.0, 52.0 -13.0, 42.0 -13.0))',
    curlopts = list(verbose=TRUE), 
    skip_validate=TRUE)

but in spocc we pass skip validate so then GBIF handles any bad WKT, like

occ(query = 'Anopheles arabiensis', 
    geometry =  'POLYGON((42.0 -26.0, 52.0 -26.0, 52.0 -13.0, 42.0 -13.0))', 
    callopts = list(verbose =TRUE))

In addition to any error that occurs - perhaps capture and give back the http request that was sent with each request, so that upon errors, user can inspect the requests to pull out if the request they thought was being sent was actually sent. not sure if its best to just give url or complete http response or something else
