Apportioning GST in the account register

[Steven Patrick]

Hi John,

At the moment they are not using Gnucash because of this limitation.  The 
way the current Gnucash customer invoice interface works with options for 
"Taxable?" and "Tax Included?" is perfect for their needs, as long as it 
can be implemented in a normal cheque account register.  Some transactions 
would be taxable and others not.

I am happy to do the development work and release it under GPL, but just 
need some assistance in homing in on the appropriate source files.

Steve
