//
// A button that sends MIRs as callbacks.
//
// There are three options for setting of user data:
// a) mCbackBeta   - a lens that will be sent as beta of the MIR;
// b) mCbackValue  - an int
// c) mCbackString - a string
//
// b) and c) are streamed into the argument part of the MIR as if the
// function signature is foo(<lens-args>, Int_t, const TString&). Thus,
// it is OK to have bar(<lens-args>, Int_t) but to access the string,
// both must be decalred in the callback method.
//
// Maybe b) and c) should be optional, but they are now as well, in a
// more pragmatic sense.
