Error handling.

Exceptions:

BadRequestError([msg])	Request is improperly formed (syntax error in the URL, POST body, etc.).
HTTPTimeoutError([msg])	The request timed out, from server overload or too broad a request.
MethodNotAllowedError([msg])	Request not allowed (such as invalid MIME type in the HTTP Accept header).
NotFoundError([msg])	The input record was not found (e.g.
PubChemHTTPError(e)	Generic error class to handle all HTTP error codes.
ResponseParseError	PubChem response is uninterpretable.
ServerError([msg])	Some problem on the server side (such as a database server down, etc.).
TimeoutError	alias of chemistry_tools.pubchem.errors.HTTPTimeoutError
UnimplementedError([msg])	The requested operation has not (yet) been implemented by the server.
