+* Description:
+* This maps Symbian OS memory management onto Icu Umemory functions
+* Memory is allocated from the shaper internal heap, which has been saved in the TLS.
+* If there is no memory available these memory functions leave, this is caught in the shaper wrapper.
+* For debugging there is an alternative set of functions which log memory allocations
