 * \author Sathyaprakash, B.S.
 *
 * Given the parameters of a template bank find the longest template
 * in the bank. This is done by looking at the duration for which
 * a signal corresponding to smallest masses lasts. One simply calls
 * the \c LALInspiralWaveLength code for a system consisting
 * of two stars each of mass <tt>mMin.</tt>
