svmkR 1.1

Added bug fix by @felippelazar to fix processing of drop-down menu type questions.

svmkR v1.0

NEW: Weight surveys using available population targets. Ex:
- weight_to(): simple canned function crosswalk a survey to an available target population and then weight to that distribution
- list_targets(): list target population distributions available in our package
- read_target(): read in a target available in our package
NEW: Added ability to reverse engineer skip rules (find_skip_rules()) from survey responses based on completion patterns.
NEW: Added demographic variable re-coding module
Unit tests added for all modules.
Stabilized some banner creation code.
pkgdown web page created for package.
End-to-end tutorial created via vignette("svmkR").

svmkR v0.3

Added modules to create surveys from this package. Ex:
- read_qdoc(): read a questionnaire from txt file
- upload_qdoc(): upload questionnaire file
Separate write_banners() into write_banners() and upload_banners()

svmkR v0.2.2

Fixed a bug in downloading a survey with named columns (i.e. col_names = "name")
parse_survey() properly parses multi-answer matrix questions (one column for every question-row-column triplet)
