An implementation of DataModel based on an array.
The Gda::DataModelArray object is a data model which internally uses a GArray to index all its rows (represented as Gda::Row objects). In this data model, all the data is stored in memory, which can be a memory limitation if the number of rows is huge. This type of data model is easy to use to store some temporary data, and has a random access mode (any value can be accessed at any time without the need for an iterator).
