Performs a query for a single content object.

@throws \eZ\Publish\API\Repository\Exceptions\NotFoundException if the object was not found by the query or due to permissions
@throws \eZ\Publish\API\Repository\Exceptions\InvalidArgumentException if Criterion is not applicable to its target
@throws \eZ\Publish\API\Repository\Exceptions\InvalidArgumentException if there is more than than one result matching the criterions

@param \eZ\Publish\API\Repository\Values\Content\Query\Criterion $filter
@param array $languageFilter - a map of language related filters specifying languages query will be performed on.
Also used to define which field languages are loaded for the returned content.
Currently supports: <code>array("languages" => array(<language1>,..), "useAlwaysAvailable" => bool)</code>
useAlwaysAvailable defaults to true to avoid exceptions on missing translations.

@return \eZ\Publish\SPI\Persistence\Content
Performs a query for a single content object .
