/** \brief Class to watch for user-interrupt (SIGINT, ctrl-C)
*
* A class to watch for SIGINT.
*
* Creating an instance of the class ensures that the Mesquite
* handler for SIGINT is registered. When all instances are
* destroyed, the Mesquite handler is removed. The intent is
* that each interruptable API declare an instance on the stack.
* This way the handler is automatically unregistered when the
* API returns. For example:
* <code>
* void my_api( MsqError& err )
* {
* MsqInterrupt interrupt;
* ... //do stuff
* return;
* }
* </code>
