Availability API response format differs from documentation

[GoogleCodeExporter]

The response object has properties to indicate number of available copies, 
number of holds, and number of copies owned, however if a count is zero, the 
related property is absent. This formatting differs from the documentation 
which indicates the property will always be present even for zero count.

The fix would be to normalize the format, ie, add in the property with zero 
count, so that the code can rely on a fixed format.

The quick fix is to substitute a zero when the property is absent, but this has 
to be done everywhere the property value is needed. A better fix is to 
'normalize' the property at one place in the code.

As a result of the quick fix, this issue is now downgraded. Refactoring of the 
code is needed to make the fix more generic so that it will be less of a 
maintenance issue.

The result of apiAvailability has been augmented to have zero numbers of avail. 
copies, holds, and copies owned.
