qdaR: Read and Analyse Qualitative Coding Exported from Zotero

Reads the versioned exchange files written by the Zotero plugins 'zotQDA' and 'qdaZ' – coded fragments, code systems, coding histories and team-consensus results – validates them against the shipped contract, and reproduces the plugin's graphics with 'ggplot2'. Adds what those plugins deliberately leave out: six agreement coefficients with bootstrap confidence intervals, the reliability of the segmentation itself, chi-squared tests of code by group tables with effect sizes, correspondence analysis, multidimensional scaling and hierarchical clustering of codes. Projects from other programs can be read through the 'REFI-QDA' interchange standard <https://www.qdasoftware.org/>, which makes those analyses available to users of established software that does not offer them; the subset a '.qdpx' supports is reported on import. Reference files are included, so every function can be tried without a Zotero installation.
