Overview of XQuiSoft Data Using the Provider Pattern (Open Source)

Note, In order to build this project depends on another open source 
project on sourceforge called xqs-provider.

** 2.2
+ demo project finally updated to utilize latest features.
+ documentation (word document) updated recommending latest features (in 2.0)
	with recommended design shown in updated demo project.

** 2.1
+ more robust handling of null on return parameter values.
+ new Oracle client implementation (separate project - dll output)

** 2.0
+ Added method overloads to Procedure that take parameter constructor values, 
including Value for the case when db 'maps' are not being used.
+ Added DbContext.ExecuteReader, DataProvider.ExecuteReader, and the same for 
the SqlClient versions.  This feature was made possible by the DbContext 
concept (added in v1.5.5000.0).  It would have been difficult to manage beforehand.
+ Aded DbContext.Execute overload tht takes a method delegate in place of an IDataFactory
instance.  Same overload was added to DataProvider and SqlDbContext.

** 1.6.5000.0
+ removed DataProvider.Name overload and call base.Initialize from Initialize
+ fixed bug - DataProviderCollection constructor now passes correct type to base class.

** 1.5.5000.0
+number sychronized with rest of this XQuiSoft core release
+References the updated Provider pattern implementation in
XQuiSoft.Provider v 1.5.5000.0
+Added DbContext class.  This class is used when multiple data
operations need to be wrapped into a single transaction.  It
contains the implementations of all the Execute commands from
DataProvider.
+DataProvider adds abstract method GetContext().
+DataProvider delegates Exectute method calls to a new instance
returned from GetContext().  Essentially these are useful when
only a single db call needs to be made that is not part of a
transaction.  This also provides backward compatibility for code
that used these before.
+DataProvider.BeginTransaction was removed.  Instead create a new
DbContext and BeginTransaction on it.
+DataProvider.CommitTransaction was removed.  Use a DbContext instead.
+DataProvider.RollbackTransaction was removed.  Use a DbContext instead.

** 1.3.5000.0
+Added DataProvider abstract method CheckConnectability(...), 
also added to SqlDataProvider.
+use ProviderHelper to read configuration values

**1.2.5000.0
Updated to use the new object pooling feature of the provider component.

**1.1.5000.0
Added a Default property to DataManager.Providers.  This allows
access to the default provider as defined in the configuration.
This is not necassarily the connection with a name of 'Default'.
Now any other classes that use the DataManager do not have to
explicitely define which connectionName they wish to use.
