// This API currently manages all user entities to be managed. This allows users of the service to change required entities and processes.
//
// The entities in question:
//
// - Client - A client is a single client of the Doczy project, all configurations and clients for a client will be in reference to the respective client.
//
// - Collector - A collector specifies the required queries for export for a given client.
//
// - Sample - A sample is a subset of documents to be used for testing. When it is active a client will only process documents in the sample.
//
// - Query - A query is a block of processing of data which takes an input and produces an output.
//
// - Export - An export is a manually started process which outputs the results for a client to a given location.
