/* We are making the following template class for serveral reasons. Firstly,
34
* we want to keep the main ostream code neat and tidy. Secondly, we want it
35
* to be easy to do partial specialization of the ostream code so that it can
36
* be expanded and put into the library. This will allow us to make application
37
* code smaller at the expense of increased library size. This is a fair
38
* trade-off when there are multiple applications being compiled. Also, this
39
* feature will be used optionally via configuration options. It will also
40
* allow us to keep the code bases in sync, dramatically simplifying the
41
* maintenance required. We specialized for char because wchar and others
42
* require different scanf functions
