Detailed Description

The primary error handler for ecl libraries.

This class is mostly used as the return type for ecl functions to indicate errors.

Error f(const int &i) {
   if ( i == 3 ) {
       return Error(NoError);
   else {
       return Error(OutOfRangeError);
   }
}

// code

Error error = f(5);
if ( error.flag() != NoError ) {
    std::cout << error.what() << std::endl; // OR
    error.print(LOC);   // for a verbose message with code location added.
}

Alternatively the class can be inherited and the verbose messages overloaded. Refer to the TimeError class in ecl_time_lite for an example.
