 Description

    This provides the main calculator functionality


********************************************************************************
 $History: MmiCalculatorMain.c

	25/10/00			Original Condat(UK) BMI version.

	xrashmic 20 Oct, 2005 MMI-SPR-33845
	To display BACK softkey when no more character are left in the calulator editor

	Oct 20, 2004    REF: CRR 25755 xnkulkar
	Description: calculator -divide by zero operation is allowed.
	Fix:	Display "Not Allowed" message when user tries to divide a number by 0 and do not perform the
			     division. Also, show the editor again so that user can enter a number other than 0.
