/**
* Retrieves a curriculum inventory in a data structure that lends itself for an easy transformation into
* XML-formatted report.
*
* @param CurriculumInventoryReportInterface $invReport The report object.
* @return array An associated array, containing the inventory.
* Data is keyed off by:
* 'report' ... The inventory report entity.
* 'institution' ... An object representing the curriculum inventory's owning institution
* 'events' ... An array of events, keyed off by event id. Each event is represented as assoc. array.
* 'expectations' ... An associative array of arrays, each sub-array containing a
* list of a different type of "competency object" within the curriculum.
* These types are program objectives, course objectives and session objectives.
* The keys for these type-specific sub-arrays are:
* 'program_objectives'
* 'course_objectives'
* 'session_objectives'
* 'framework' ... The competency framework data set.
* 'includes' ... Identifiers of the various competency objects referenced in the framework.
* 'pcrs_ids'
* 'program_objective_ids'
* 'course_objective_ids'
* 'session_objective_ids'
* 'relations' ... Relations between the various competencies within the framework
* 'program_objectives_to_pcrs'
* 'course_objectives_to_program_objectives'
* 'session_objectives_to_course_objectives'
* 'sequence_block_references' ...relationships maps between sequence blocks and other curricular entities.
* 'events' ... maps sequence blocks to events
* 'competency_objects' .. maps sequence blocks to competency objects
*
