example library calls

[Danny Holstein]

Developers; 

I can't seem to find an example of how to call the Gnucash libraries. I'd like to write a program that posts invoices from a web-based shopping cart, and I can imagine a POS program or ERP program using the library for the GL backend. 

I would expect examples to be in a top level examples directory, with language-based subdirectories such as C and python. 

I had tried a search of the archive, but the search seemed broken and yielded no results.
