    Ability to specify longer fieldnames
    When creating a new field, the user should be able to specify a fieldname longer than 10 characters, say 25, at least. 

         When I am working with points acquired with two datums, and I want to calculate the difference in elevations between the two, I want to name the field as "Delta_z_N83_to_WGS84".
