This method generates new names with an index and returns the first name it finds that passes the given validity check. May be used, for example, to create a new name for a copied project, eg. My Project_Copy_9.

Parameters:

originalName - Original name.

lengthLimit - Maximum length that is allowed for the name.

validityCheck - A predicate that checks whether a given generated name is allowed, eg. whether a project with that name exists already.

Returns:

A new name that passes the validity check.

Throws:

LimitExceededException - When no new unique name could be generated.
