#65
Separated the various demos into types cause it was showcasing too many things. And added main.js for enabling search to the ComboRow

XML code works, because of these lines
<property name="expression"> <lookup type="GtkStringObject" name="string"/> </property>
But wasn't able to replicate these lines to blueprint .

I'll need some time to think about what we want to do for #65
I had in mind to have one demo per row type but it might be too much

@Sahil-Shadwal avoid using your main branch for submitting PRs - it's easier if it tracks Workbench main.

If you want you can file a new PR for

Add search to the ComboRow demo

I think that should be straightforward
