function [cfg,csBase] = mha_findid( mhah, csIds )
% MHA_FINDID - find first entry matching an ID or a list of IDs.
%
% Usage:
% cfg = mha_findid( mhah, csIds )
%
% - mhah : MHA handle
% - csIds : string or cell string array of IDs to be searched (optional)
%
% - cfg : structure with fieldsnames equal to IDs, values are
% configuration paths
% - csBase : list of all plugins with IDs
