* Numeric:
* YYYYMMDD - Shows all entries from YYYY-MM-DD.
* If DD is "00", it will show all entries from that month.
* If DD is any other number, it will show entries of that specific day.

* Other (null, 3-dimensional Array, ...):
* Entries newer than $modified_since will be fetched
* full (boolean) Indicates if the full entry will be fetched (body+extended: TRUE), or only the body (FALSE).
* limit (string) Holds a "Y" or "X, Y" string that tells which entries to fetch. X is the first entry offset, Y is number of entries. If not set, the global fetchLimit will be applied (15 entries by default)
* fetchDrafts (boolean) Indicates whether drafts should be fetched (TRUE) or not
* modified_since (int) Holds a unix timestamp to be used in conjunction with $range, to fetch all entries newer than this timestamp
* orderby (string) Holds the SQL "ORDER BY" statement.

* noCache (boolean) If set to TRUE, all entries will be fetched from scratch and any caching is ignored
* noSticky (boolean) If set to TRUE, all sticky entries will NOT be fetched.
* select_key (string) Can contain a SQL statement on which keys to select. Plugins can also set this, pay attention!
* group_by (string) Can contain a SQL statement on how to group the query. Plugins can also set this, pay attention!
* returncode (string) If set to "array", the array of entries will be returned. "flat-array" will only return the articles without their entryproperties. "single" will only return a 1-dimensional array. "query" will only return the used SQL.
* joinauthors (bool) Should an SQL-join be made to the AUTHORS DB table?
* joincategories (bool) Should an SQL-join be made to the CATEGORIES DB table?
* joinown (string) SQL-Parts to add to the "JOIN" query

* [PRINTING]
* template: (string) Name of the template file to print entries with
* preview: (boolean) Indicates if this is a preview
