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