+ * Terminology for repair scenarii:
+ *
+ * - A 'repaired' item is an item that was generated and that needs to be repaired because the plan changed for that subscription on that period of time
+ * - The 'repair' item is the item that cancels the (to be) repaired item; the repair item amount might not match (to be) repaired item because:
+ *   * the (to be) repaired item was already adjusted so we will only repair what is left
+ *   * in case of partial repair we only repair the part that is not used
+ * - The 'reparee' item is only present on disk-- in the existing item list -- in case of full repair; in that case it represents the portion of the item that should still
+ *   be invoiced for the plan of the repaired item. In case of partial repair it is merged with the repair item and does not exist except as a virtual item in the proposed list
+ *
+ *
+ *
+ * Example. We had a 20 subscription for a given period; we charged that amount and later discovered that only 3/4 of the time period were used after which the subscription was cancelled (immediate canellation)
+ *
+ * Full repair logic:
+ *
+ * Invoice 1:                   Invoice 2:
+ *           +20 (repaired)             +5 (reparee)
+ *           -20 (repair)
+ *
+ * Partial repair logic:
+ *
+ * Invoice 1:                   Invoice 2: (N/A)
+ *           +20 (repaired)
+ *           -15 (repair)
+ *
+ * The current version of the code uses partial repair logic but is able to deal with 'full repair' scenarii.
