/// All the actions and transactions are programmed in JavaScript. The AvocadoDB
/// provides a fluent interface in JavaScript to access the database directly
/// together with a set of support function.  A fluent interface is implemented
/// by using method chaining to relay the instruction context of a subsequent
/// call.  The AvocadoDB defines the following methods:
///
/// - selection by example
/// - field selection (aka projection)
/// - sorting
/// - pagination of the result-set
///
/// Advanced topics are
///
/// - geo coordinates

/// @section FirstStepsFI First Steps

/// All documents are stored in collections. All collections are stored in a
/// database.
///
/// @verbinclude fluent41
///
/// Printing the @VAR{db} variable will show you the location, where the
/// datafiles of the collections are stored by default.
///
/// Creating a collection is simple.  It will automatically be created
/// when accessing the members of the @VAR{db}.
///
/// @verbinclude fluent42
///
/// If the collections does not exists, it is called a new-born. No file has
/// been created so far. If you access the collection, then the directory and
/// corresponding files will be created.
///
/// @verbinclude fluent43
///
/// If you restart the server and access the collection again, it will now show
/// as "unloaded".
///
/// @verbinclude fluent44
///
/// In order to create new documents in a collection, use the @FN{save}
/// operator.
///
/// @verbinclude fluent45
///
/// In order to select all elements of a collection, one can use the @FN{all}
/// operator.
///
/// @verbinclude fluent46
///
/// This will select all documents and prints the first 20 documents. If there
/// are more than 20 documents, then @CODE{...more results...} is printed and
/// you can use the variable @VAR{it} to access the next 20 document.
///
/// @verbinclude fluent2
///
/// In the above examples @CODE{db.examples.all()} defines a query. Printing
/// that query, executes the query and returns a cursor to the result set.  The
/// first 20 documents are printed and the query (resp. cursor) is assigned to
/// the variable @VAR{it}.
///
/// A query can also be executed using @FN{hasNext} and @FN{next}.
///
/// @verbinclude fluent3
