projectable 0.0.6

Deprecated spec_col_freq(). This function was implemented in a fairly unsafe way. It is being dropped without deprecation since it is purely a convenience function, the usefulness of which is limited anyway.
prj_gt() and prj_flex() now attempt to add gt and flextable (respectively) to the path and throw an error if this cannot be done.

projectable 0.0.5

Fixed bug in col_binomial() that prevented it from accepting NA as an argument to n or N.

Limited confidence intervals in col_binomial() to the range [0, 1] (#27). Previously, it was possible to observe ci_lower < 0 or ci_upper > 1 when computing confidence intervals with a finite population correction. However, such values are not sensible. Now, col_binomial() will force such values to 0 or 1.

Implemented new_col function to allow users to make their own col objects (#16).
Added rounding to projections (#11).
Add weight argument to col_freq to allow for weighted frequencies.
Implemented prj_flextable() for projecting as a flextable object (#12).
Implemented a col_row class and associated col_row() function to allow special handling of dataframe columns representing row labels. (#14).
Reimplemented the col_binomial() function using asbio::ci.p() primarily to allow the user to select a parameter estimation method, and added a note field to the col_binomial class to store information on how the parameters were estimated. (#8, #9).
Made projectable_col class extensible by introducing the new_col() function. (#16).
Added a NEWS.md file to track changes to the package.
