Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
