/**
 * A record of a medication that is being consumed by a patient. A
 * MedicationStatement may indicate that the patient may be taking the
 * medication now or has taken the medication in the past or will be taking the
 * medication in the future. The source of this information can be the patient,
 * significant other (such as a family member or spouse), or a clinician. A
 * common scenario where this information is captured is during the history
 * taking process during a patient visit or stay. The medication information may
 * come from sources such as the patient's memory, from a prescription bottle,
 * or from a list of medications the patient, clinician or other party
 * maintains.
 * 
 * The primary difference between a medication statement and a medication
 * administration is that the medication administration has complete
 * administration information and is based on actual administration information
 * from the person who administered the medication. A medication statement is
 * often, if not always, less specific. There is no required date/time when the
 * medication was administered, in fact we only know that a source has reported
 * the patient is taking this medication, where details such as time, quantity,
 * or rate or even medication product may be incomplete or missing or less
 * precise. As stated earlier, the medication statement information may come
 * from the patient's memory, from a prescription bottle or from a list of
 * medications the patient, clinician or other party maintains. Medication
 * administration is more formal and is not missing detailed information.
