getValues: get system quantity (e.g. startValue, inflowRate, washOut)...
In microPop: Process-Based Modelling of Microbial Populations

get system quantity (e.g. startValue, inflowRate, washOut) for all state variables (convention is that microbes are before resources)

getValues(
  sysInfoMicrobes,
  sysInfoRes,
  stateVarNames,
  quantity,
  strainNames,
  microbeNames,
  resourceNames,
  numStrains
)

`sysInfoMicrobes`	sys info dataframe for microbes
`sysInfoRes`	sys info dataframe for resources
`stateVarNames`	Vector of names of all the state variables
`quantity`	String. Name of quantity to get value for e.g. 'startValue'
`strainNames`	Vector of strings of strain names
`microbeNames`	Vector of strings which contains the names of the microbial groups in the system e.g. c('Bacteroides','Acetogens')
`resourceNames`	Vector of strings which contains the names of the resources in the system
`numStrains`	Integer. Number of strains per group
