subroutine  Multispecies_getSumInv (property, value, weights, speciesMask) 
subroutine Multispecies_getSumInv  (  integer, intent(in)  property, 
real, intent(out)  value,  
real, dimension(:), intent(in), optional  weights,  
integer  speciesMask  
) 
Given a property name and an array of weights, compute the weighted sum of the inverse of a chosen property.
SumInv = sum over species( weight / propertyValue)
Weights should be an array of length equal to the number of species (NSPECIES). If not provided, weights are assumed equal to one.
The default, is to return the weighted sum for all species. A user, however, by passing in the optional argument speciesMask can choose to include only species of interest.
speciesMask is an array of integers of size Number of Species in length The mask works inclusively, that is the user specifies species that should be _included_ in the calculation.
For example: in a given simulation if there are 4 defined species NI56, CO61, MG23, FE51 and the user wants to get a weighted sum of just NI56 and FE51 then the user would pass in the speciesMask arguement where speciesMask(1) = NI56 speciesMask(2) = FE51 speciesMask(3) = UNDEFINED_INT speciesMask(4) = UNDEFINED_INT
Order does not matter, however the order of the weights array MUST be the same as the mask.
The property is an integer because it is defined in Multispecies.h description property(defined as integer in Multispecies.h)  numTotal A Total number of protons and neutrons in nucleus numPositive Z Atomic number; number of protons in nucleus numNeutral N Number of neutrons numNegative E Number of electrons bindingEnergy EB Binding energy adiabatic index GAMMA Ratio of heat capacities: Cp / Cv
property  name of property as defined in Multispecies.h value  returned the sum of the inverses of a given property from routine weights  an optional array of length 1 or NSPECIES holding the weights for each species. If not provided, weight=1 is assumed. If a weights array of size 1 is provided, its value is applied to all species. speciesMask  an optional array of length NSPECIES specifying the wanted species for the average calculation
NOTES
Species properties are normally set in Simulation_initSpecies. The simulation's Config file defines the number and name of species, as in SPECIES AIR SPECIES SF6
