Detailed Description
This proxy takes multiple source models and concatenates their rows.
In other words, the proxy will have all rows of the first source model, followed by all rows of the second source model, etc.
Only flat models (lists and tables) are supported, no trees.
All models are assumed to have the same number of columns. More precisely, the number of columns of the first source model is used, so all source models should have at least as many columns as the first source model, and additional columns in other source models will simply be ignored.
Source models can be added and removed at runtime, including the first source model (but it should keep the same number of columns).
Dynamic insertion and removal of rows and columns in any source model is supported. dataChanged, layoutChanged and reset coming from the source models are supported.
At the moment this model doesn't support editing, drag-n-drop. It could be added though, nothing prevents it.
This proxy does not inherit from QAbstractProxyModel because it uses multiple source models, rather than a single one.
