cellTemplate function with argument

• You have searched the open issues to see if this bug has been filed before. We don't want duplicate issues.
• You have reviewed the tutorials and documentation to ensure you are using the grid correctly. ui-grid.info
• You are using the latest version of the grid. Older versions are not patched or supported.

It would be interesting to be able to define 'cellTemplate' with a function like the example below.

Example:

//The dataItem variable is the same thing as row.entity
cellTemplate: function(dataItem: {}) {
  return '<h1>{{dataItem | json}}</h1>';
}

I would like to have this feature, because I abstracted the usage of ui-grid in my own component and I want something more generic in case we want to replace ui-grid by another grid in the future. I don't want to use 'row.entity' (neither COL_FIELD or getCellValue...) because ag-grid or kendo or any other grid have different signatures, a function returning the dataItem Object is more reusable. If some day we decide to replace ui-grid by another one (could be ui-grid v4!), and if 'row.entity' was replaced by something else, then we will be screwed. With a function(datItem) in 'cellTemplate', we will have just one place where we will need to change that: in the generic component only...
