PR Approved
Tested using the custom 4.1.0 build given by @pec1985 .
As of now only "ti.geo " events are filtered by using Ti.Analytics.filterEvents(['ti.geo']) in the app.
Checked the following:

1. We get ti.geo events with out the filterEvents method -- Passed. We got ti.geo as expected.
2. We get ti.geo events with the filterEvents method -- Passed. We did not get ti.geo which is expected as they are filtered.
3. Any other events other than ti.geo are filtered -- Passed. No other events are filtered apart from ti.geo.
