#173 delIndex and getSchema raise AttributeError

[Shaun McCance]

Lines 817-818 of main.py contain the following:

delIndex = _sqlmeta_attr('delIndex', 2)
getSchema = _sqlmeta_attr('getSchema', 2)

This makes delIndex and getSchema in an SQLObject
instance reference to the corresponding members of
sqlmeta, possibly spitting out a DeprecationWarning.
But delIndex and getSchema don't exist in sqlmeta.
This causes my code to die with an AttributeError when
trying to do introspection on SQLObject-derived classes.
