  /** \brief A C++ main code to test the <a href="classatm_1_1SpectralGrid.html">SpectralGrid</a> Class 

   *

   *   Test 1 is structured as follows:

   *         - Creates a pointer called "sgPtr1" of objects belonging to the class <a href="classatm_1_1SpectralGrid.html">SpectralGrid</a>

   *         - Initializes that pointer with a first object created with the <a href="classatm_1_1SpectralGrid.html#a1">this</a> constructor.

   *         - The pointer has then one element . On this element, several things are checked using the following operators of the class: 

   *           <a href="classatm_1_1SpectralGrid.html#z14_6">getRefFreq(unsigned int spwId)</a>, 

   *           <a href="classatm_1_1SpectralGrid.html#z14_8">getChanSep(unsigned int spwId)</a>, 

   *           <a href="classatm_1_1SpectralGrid.html#z14_0">getNumSpectralWindow()</a>, and 

   *           <a href="classatm_1_1SpectralGrid.html#z14_2">getNumChan(unsigned int spwId)</a>.

   *         - An rrror message is expected when trying getNumChan(1) because there is no spectral window number 1.

   *         - Finally, the operators <a href="classatm_1_1SpectralGrid.html#z14_22">isRegular(unsigned int spwId)</a>, 

   *           and <a href="classatm_1_1SpectralGrid.html#z14_25">getAssocSpwId(unsigned int spwId)</a> are tested.

   *  

   * The ouput of this test should be as follows:

   *

   * <b>

   * SpectralGridTest: Test 1: <br>
