monocov/MonoCovMain.cs

//
// TODO:
// - the line number information generated for some methods is funky, like
//   System.Text.Encoding::get_ASCII
// - the line number information for System.CurrentTimeZone:GetDaylightChanges
//   contains a 0->196 mapping !!!
// - the line number information for life.cs does not contain anything for line
//   38.
// - when a method signature consists of multiple lines, the begin_line for
//   the methods seems to be the last line of the signature, instead of the 
//   first.
// - the line number information does not contain columns, making it
//   impossible to determine coverage for code like this:
//     if (something) { something }
// - why doesn't some line numbers do not appear in stack traces ????
