Plan for CRAN release

[Kertoo]

The following list describes changes that are to be made before we can release singleRcapture to CRAN:

• Complete plan for 0.2.0.
  Add more error messages in:
• Fitting especially optim.
• Deviance residuals -> numerical inversion of $\mu(\boldsymbol{\eta})$ function.
• singleR class methods.
• Add checks for very low numeric values of weights $(< \varepsilon_{\text{weights}}$ maybe 1e-12 by default) to make IRLS more stable.
• Speed up simulate in "new" family functions.
• #40
• predict method.
• Examples for estimate_popsize.fit.
• Move creation of starting parameters to family functions.
• Standardization of syntax.
• Check for full rank of $\boldsymbol{X}$ matrix, currently it is assumed apriori that $\boldsymbol{X}$ is full rank.
• Standardize factors in exported data frames.

Update: Plan for 0.2.0 is completed. I'll pull after rest of these points are completed and then submit it to CRAN

Closing after CRAN submission.
