Dropletcombustion5 is the version which floor the small mass fraction(smaller than massfractionTolerance) to 0.00 ; 
Dropletcombustion6 is the version where the Antoine parameters are those of water ;
Version 7 change the hardcode some tolerance after ignition:Max T> 1800K
version 8: the x in the main.cpp is changed to the maxGradPosition
version 9: isothermPosition function in residue.cpp is revised for droplet combustion
version 10: both xOld and x is the position of isoTherm ; 
version 11: both xOld and x is the position of maximum curvature;
DropletCombustionTest: test the variables in the program 
DropletCombustionTest1: Multiple the l function by 10.0
DropletCombustionTest2: Multiple the l function by 100.0 and remove print timeScale;
DropletCombustionTest3: Multiple the l function by 10.0 and print the maxTemp and add criteria for regrid
DropletCombustionTest4: dxRatio to be 1.0e-2 and delta_T to be 150 [K]
DropletCombustionTest5: dxRatio to be 1.0 and print x and xOld temperature, modified the fillGrid function;
DropletCombustionTest7: JJRG has been implemented;
