Change Description

Constructor and destructor are defined here:

fprime/Os/IntervalTimerCommon.cpp

Lines 19 to 24 in 4f65e1e

	IntervalTimer::IntervalTimer() {
	memset(&this->m_startTime,0,sizeof(this->m_startTime));
	memset(&this->m_stopTime,0,sizeof(this->m_stopTime));
	}
	IntervalTimer::~IntervalTimer() {}

.

This removes the errant implementation of them in the baremetal stub.
