Revert "Fix to package documentation."

 - Original statement about complexity holds. The O*((n-1)^3) complexity
   is when n is the dimension of a normalized weight vector, in which
   case the *sampling* space is of dimension n-1.

This reverts commit a874c4fc5b5447cb92fb930295a77b1be3227337.
gitignore
Use all.equal in example
Minor code style / consistency fixes
Prefix all C symbols with hitandrun_

To prevent name clashes with other packages
Start documenting new features
Add docs for createTransform and solution.basis
Bugfix
Separate solution.basis tests from documentation
Clean up solution.basis example
Add generalized hitandrun() interface

 - handles both equality and inequality constraints transparently
 - also add simplexConstraints() to make sampling from the simplex easier
 - documentation updated to reflect changes
Parameterize seed point generation
Offer specific re-entrant version of generalized HAR, simplify default

 - har.init() -> har.run() -> har.run() vs hitandrun()
Add findInteriorPoint to exports
Update documentation & keywords
Update DESCRIPTION and add NEWS
Doc fixes
Import instead of depend rcdd
Remove scratchpad files
Makefile: rebuild on test changes
