Move static methods for resolving sort and filter strings from KendoGrid class to static extension method class.   This will allow use of filter and sort to resolve a queryable outside of the KendoGrid class (in a service method for example).

Fix missing  var caseMod = "";  in GetExpression causing compilation error (seems to have been accidentally deleted in last commit)

Rename properies Data and Count to be consistent with standard .NET naming conventions for properties.

Remove redundant parameter from 3rd constructor of KendoGrid class, and add docstrings
Add example of extension method usage
