Minor changes to remove warnings and errors when building as cran

This should allow for submission to CRAN when time comes. Few minor tweaks may be required as the following are still happening:

1. when running: R CMD check --as-cran KinformR --ignore-vignettes
   I get the warning:

* checking package subdirectories ... WARNING
Found the following directory with the name of a version control directory:
  ./.git
These should not be in a package tarball.

Despite the file .Rbuildignore including this dir

2. when running: R CMD check --as-cran KinformR
   I get the warning:

* checking files in ‘vignettes’ ... WARNING
Files in the 'vignettes' directory but no files in 'inst/doc':
  ‘KinformR-penetrance_and_ibd.Rmd’ ‘KinformR-variant_scoring.Rmd’

These can both be addressed by making a copy of the folder, removing the .git dir and moving the built vignettes to the specified location. However, this is more manual interaction than I would like so I will keep looking for programatic solutions to these warnings.

Note that running R CMD build KinformR builds the tarball KinformR_0.1.0.tar.gz without warning.

Closes the following issues

• CRAN submission #28

Pre-release notes

• Post-release tasks
  • Complete the final build of 0.1.0
  • Do the submission to cran
