kfa 0.2.2

*New features and adjustments:

loading flag based on absolute value of loading
The degrees of freedom calculation in find_k is now based on a CFA model rather than EFA
Can toggle plots off when generating report - temporarily changed default to off to limit strong dependency with archived package

kfa 0.2.1

*New features and adjustments:

data argument added and variable argument re-defined as specifying column names in data
The sampling.weights argument is passed appropriately to lavaan and incorporated into the analysis
Changed name of threshold argument to the more specific name min.loading
Adjusted order of custom.cfa models in flag table to match the order in the model fit table of the report

New features and major adjustments:
- Users can keep cross-loading variables by setting simple = FALSE and specifying a threshold
- Default test statistic and fit indices switched from naive to scaled versions (mean and variance adjusted)
- In agg_model_fit, changed default index to "all"
- model_structure, get_std_loadings, and index_available are exported for use
- Tables sorted based on order of variables and models provided by user rather than alphabetical
Bugs and background
- Deleted Rd files for non-exported functions - silly me :)
- Fixed rotation error bug in run_efa
