Jasmina implemented eclipse/transit choice path.  Added eclipse.c with functions for eclipse calculation: totaltau_eclipse, tau_eclipse, eclipse_intens, emergent_intens, printecl, eclipsepath.  In transit.c path solution variable and IF statement for eclipse/transit choice are added.  In argum.c new parameter is set, new solutions is defined and read.  In Rules.mk eclipse source file is added for compiling.  In proto_argum.h new function defined in argum.c is declared.  Proto_eclipse.h is made with function defined in eclipse.c.  In structure_tr.h eclipse ray solution is made, new parameter is added to transithint structure and transit structures, new type ray solution enum variable is defined.  In transit.h eclipse ray solution and proto_eclipse.h are included.  In Makefile new PUFLAG is added so the code can compile with 'make transit'.
