Purpose of the thorn
--------------------

One of the test thorns for function aliasing (TestFunctions1B, 
TestFunctions1B and TestFunctions2)

Test Thorns for Function Aliasing
---------------------------------

TestFunction1A: provides the functions

  PrintMe(CCTK_REAL) 
	- with TestFunctions1A_PrintMe
  SumMe(CCTK_REAL,CCTK_REAL) 
	- with TestFunctions1A_SumMe
  AddVector(CCTK_INT,CCTK_REAL:ARRAY)
	- with TestFunctions1A_AddVector
  PrintString(CCTK_INT, CCTK_STRING)
	- with TestFunctions1A_PrintString
  Print2String(CCTK_INT,CCTK_STRING,CCTK_STRING)
	- with TestFunctions1A_Print2String  
  Print3String(CCTK_INT,CCTK_STRING,CCTK_STRING,CCTK_STRING) 
	- TestFunctions1A_Print2String

TestFunction1B: provides the functions

  PrintMe(CCTK_REAL)
	- with TestFunctions1B_PrintMe
  SumMe(CCTK_REAL,CCTK_REAL)
	- with TestFunctions1B_SumMe
  ReturnCCTKTime(CCTK_POINTER)
	- with TestFunctions1B_ReturnCCTKTime

TestFunction2: 

  Uses the aliased functions from both C and Fortran routines
