/**
 * Issue list functions and data structure building.
 *
 * The data structure is the $ISSUE_TYPES array.
 * The $ISSUE_TYPES array is built from the issue_types sql table and provides
 * abstraction of issue types to allow customization.
 * <pre>Attributes of the $ISSUE_TYPES array are:
 *  key - The identifier. (Do NOT create element with token 'prescription_erx' since this is reserved by NewCropRx Module that leverages lists_touch table to support MU calculations)
 *  0   - The plural title.
 *  1   - The singular title.
 *  2   - The abbreviated title (one letter abbreviation).
 *  3   - Style ('0 - Normal; 1 - Simplified: only title, start date, comments and an Active checkbox;no diagnosis, occurrence, end date, referred-by or sports fields.; 2 - Football Injury; 3 and 4 are IPPF specific)
 *  4   - Force show this issue category in the patient summary screen even if empty (setting to 1 will force it to show and setting it to 0 will turn this off).
 *  5   - ACO for this type, for example "patients|med".
 *
 * Note there is a mechanism to show whether a category is explicitly set to
 * 'Nothing' via the getListTouch() and setListTouch() functions that store
 * applicable information in the lists_touch sql table.
 *
