Added sample based mutual information computation
1. RHT case now compatible with the paralell identifiability computation
2. Added quadrature computation
Other edits:
1. Added importance sampling example in quadrature
Notes:
1. Noise is structured such that the boundary points are not affected.
Minor updates:
1. Added plotting function for MI
1. enthalpy and internal energy match Cantera
Description:
Combustion model for n_dodecane and methane are added.
Correct S-curve is obtained for the methane case.
For n_dodecane a sudded increases is noted.
Description:
Leaning model for ignition time added for
Description:
Added subsampling to compute the identifiability of the model.
Theoretical estimates were also altered to include sub sampling
Description:
1. Modified the ignition time definition to gradient based, i.e.
location with the highest change in temperature is the ignition time.
2. Conformed the model output to be in sync with the model
   identifiability computation.
3. Added log file
Added measurement uncertainty to the computation of Sobol Index.
Moved pull request outside the PULL_REQUEST_TEMPLATE folder
Added total sobol index computation
Add sobol index computation from the data printed
at each rank for the numerator and the denominator
Save the numerator and the denominator for the post
processing step.
This avoids on-line sobol index computation
Added variance convergence study for the Linear Gaussian case
Added Aggregate posterior computation
Added Bias and Variance convergence study for identifiability.
Added identifiability based parameter normalization
Added normalized parameter learning for ignition temerature
learning
Added the feature to skip the ranks which are not computed in sobol
index computation.
Added functionality to forward solve the sobol values
