**************************************************************************
* Name: CIccXform::Create
* 
* Purpose:
*  This is a static Creation function that creates derived CIccXform objects and
*  initializes them.
* 
* Args: 
*  pProfile = pointer to a CIccProfile object that will be owned by the transform.  This object will
*   be destroyed when the returned CIccXform object is destroyed.  The means that the CIccProfile
*   object needs to be allocated on the heap.
*  bInput = flag to indicate whether to use the input or output side of the profile,
*  nIntent = the rendering intent to apply to the profile,   
*  nInterp = the interpolation algorithm to use for N-D luts.
*  nLutType = selection of which transform lut to use
*  bUseD2BxB2DxTags = flag to indicate the use MPE flags if available
*  pHintManager = pointer to object that contains xform creation hints
* 
* Return: 
*  A suitable pXform object
