&apos;&apos;&apos;	SF_PythonHelper (aka Basic)
&apos;&apos;&apos;	===============
&apos;&apos;&apos;		Singleton class implementing the &quot;ScriptForge.Basic&quot; service
&apos;&apos;&apos;		Implemented as a usual Basic module
&apos;&apos;&apos;
&apos;&apos;&apos;		The &quot;Basic&quot; service must be called ONLY from a PYTHON script
&apos;&apos;&apos;		Service invocations: Next Python code lines are equivalent:
&apos;&apos;&apos;			bas = CreateScriptService(&apos;ScriptForge.Basic&apos;)
&apos;&apos;&apos;			bas = CreateScriptService(&apos;Basic&apos;)
&apos;&apos;&apos;
&apos;&apos;&apos;		This service proposes a collection of methods to be executed in a Python context
&apos;&apos;&apos;		to simulate the exact behaviour of the identical Basic builtin method.
&apos;&apos;&apos;		Typical example:
&apos;&apos;&apos;			bas.MsgBox(&apos;This has to be displayed in a message box&apos;)
&apos;&apos;&apos;
&apos;&apos;&apos;		The service includes also an agnostic &quot;Python Dispatcher&quot; function.
&apos;&apos;&apos;		It dispatches Python script requests to execute Basic services to the
&apos;&apos;&apos;		appropriate properties and methods via dynamic call techniques
&apos;&apos;&apos;
&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;&apos;
