Set Text in Datum Tags and GTols Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open a drawing that contains at least one view, a datum feature,
//    and a geometric tolerance.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Sets prefix, suffix, and callouts for the first GTol.
// 2. Inserts below frame text in the first GTol.
// 3. Edits below frame text.
// 4. Deletes the first line of the below frame.
// 5. Gets the datum tag label.
// 6. Examine the Immediate window.
