[Tutor] Module with Financial Functions

[Harm_Kirchhoff at mail.digital.co.jp]

A while ago I posted a message asking for a module with financial 
functions (compounded interest, annuities, IRR analysis, Depreciation 
tables).

I followed up the one feedback I got and it seems that there is not 
comprehensive module.

I am writing such a module now and I wonder, what would be the 
preferred/best/easiest place to make it available to others ?
