Unable to initialize sessions with duplicated file names

[areewitoelar]

If a project is initialized from a data location where session files/folders have the same name across different different subjects, the default selection of session ids (from folder/file name) will result in non-unique session ids.

In nansen.config.initializeSessionTable this will then cause an error in the following code block:

NANSEN/code/+nansen/+config/initializeSessionTable.m

Lines 73 to 91 in 459353b

	sessionIDs = {sessionArray.sessionID};
	if numel(sessionIDs) ~= numel(unique(sessionIDs))
	[sessionArray, wasAborted] = nansen.manage.uiresolveDuplicateSessions(sessionArray, hFigure);
	numSessionPostExclusion = numel(sessionArray);
	% Todo: Why are all duplicates excluded? I.e keep first one...
	if numSessionPostExclusion == 0
	% Todo: Add more detailed how-to solution
	error('NANSEN:InitializeSessionArray:DuplicateSessionIDs', ...
	['%d sessions were excluded because they share duplicate session IDs:\n%s\n' ...
	'Please ensure all session IDs are unique before continuing.'], ...
	numel(sessionIDs), strjoin(unique(sessionIDs), ', '));
	end
	% Todo: Rerun initialization from here if sessions were resolved
	if wasAborted
	return
	end

There are two problems here:

1. When duplicate session ids are identified, all the sessions are excluded, not just the duplicates
2. The procedure for resolving duplicates is poorly documented and not user friendly.

Proposed solution:
When creating a session table, all the detected sessions should get assigned a unique internal identifier, and then it is up to the user (potentially via some provided utilities) to clean up duplicated sessions after creating a project.
