#cs     FUNCTIONS

    About               The database is a map. The map stores some administrative keys that are for
                        internal use only. The datasets are added as a map and the passed
                        (or automatically generated) ID is their key in the DB map.

    _MapDB_New          Creates a new database map. Pass the dataset field names as semicolon-separated string or array.
                        Stores the passed field names inside. Field names are case sensitive!
                        Returns the map. The number of datasets is indicated by: $myDBMap.Count
                        The user can add an array of additional database fields. When you remove all
                        datasets from the DB, you can keep their values or delete the values as well (default).

    _MapDB_FromCSV      Creates a map database from a passed csv file.

    _MapDB_ToCSV        Stores a map database as passed csv file.

    _MapDB_Add          Adds a new dataset. Each field must be assigned a value (empty string if necessary).
                        - A maximum of 10 single values can be passed as direct parameters.
                        - Values can also be passed as an array. The number is not limited here, it only
                          has to match the defined number of fields.
                        - Values can also be passed as an map. The field names must match the field
                          names in the database definition.
                        To make the record unique, an ID must be passed.
                        If an empty string is passed instead, a consecutive numeric ID is generated.
                        The return value of the function is the ID.

    _MapDB_Modify       Modifies one or more values of a dataset.
                        If data is passed as direct parameters, array or map, an empty string must be passed
                        for values that are not to be changed. Each field must be assigned a value.
                        The fourth and certainly most common variant is to pass an assignment string of
                        the form "field1=value<DELIM>field2=value<DELIM>...".
                        Opt('GUIDataSeparatorChar') is used as <DELIM>. A sequence or number of values
                        need not be considered here.
                        Note!
                        Field names must be passed in the same notation (case sensitive) as stored
                        in the database definition.

    _MapDB_Remove       Removes a dataset or, if an empty ID is passed, all datasets from the database.
                        Returns the number of deletions.

    _MapDB_DSToString   Returns field and values of an DS by passed ID as string: "[field1] = value; [field2] = value;... "

    _MapDB_DSToArray    Returns field and values of an DS by passed ID as 2D array: [[field1,value],[field2,value],...] "

Rudimentary search functions:

    _MapDB_SearchAnd    Searches with one or more conditions passed as a string like "field1=val<DELIM>field2=val<DELIM>...".
                        All conditions must match.
                        Returns a map with one or more datasets matching the conditions.

    _MapDB_SearchOr     Searches with one or more conditions passed as a string like "field1=val<DELIM>field2=val<DELIM>...".
                        At least one condition must match.
                        Returns a map with one or more datasets matching the conditions.
