1. get the SGI STL from their site.
2. redirect all #includes with <bla> to #includes with "bla.h" so that the
SGI-STL will be used             instead of the MS-STL.
3. change places with things like 'int a[len] to' explicit heap allocations
(using new and delete)
4. change some loop-variables that had the same name within nested for-loops
(VC does not allow     this, so I changes 'i' to 'i1' and 'i2' and so on...)
5. replace the use of stringstreams (which were somehow not supported in the
SGI STL) to convert float to string, with the use of MS-Specific
functions (I used #ifndef _WIN32, so both     versions exist in the code)
