Implement a tree grid that support large dataset with sorting and filtering

[vegegoku]

We already have a lazy grid that will load the children only when the parent is expanded, so we just enhancing that implementation to provide more functionality. using any large data set with none lazy tree grid is not recommended as there is no way to make it fast.

• The TreeGrid will need to have ability to be filtered.

For this we expect the server to handle the filtering since in the result we need to include parents that might not match the filter criteria but have children that match it, for local lists filtering that way in a lazy grid makes no sense it will force traversing the whole data set recursively and it will be very slow.

• The TreeGrid will need to have ability to sort quickly.

Sorting will be executed in a lazy so children will be sorted when the parent is expanded.
