more PDS functions; new resource to monitor process_status

refactored L::Utils::get_yaml to only require args needed for construction of path/to/yaml_dir/filename to remove duplication from components requiring a get_yaml_file() method (Controllers, Model & ScriptHelpers)

added get_yaml_file method to L::Model::Base for use by L::L::R::DiagnosisConfirm; moved all instances of YAML::Tiny->read code to L::Local::Utils

moved diagnosis_confirmation_required from Local::Utils to new Local::Role::DiagnosisConfirm - didn't belong in Utils class, and function now needs to access LIMS config to load yaml files dir dynamically depending on CENTRE env param

print report function calculates composite immunohistochemistry p21/p53 result; replaced M::Request::get_previous_diagnosis_count() with get_previous_diagnoses() to supply data instead of just count, replacing redundant previous_diagnosis_data from C::Report::load(); printed reports now display 'amended report' details and highlights changed diagnosis; QueryLog creates separate logfiles for dev server user, to avoid lack of write permissions if files opened by Apache user & also to avoid polluting production logs with dev data

modified L::Base::format_first_name() for use with C::Roles::Chart::plot_hiv; fixed syntax error in hilis3 convert Role::RebuildTables

Outreach data summary displays calculated values where required; modified Outreach params chart output to accomodate calculated values; Outreach data summary template displays default vals as 'N'K', and numerical results to 3 sig figs; improved HMRN treatment options admin interface

mostly housekeeping, moving & renaming unused files, etc

added GP menu to HMRN demographics section; fixed more circular refs in C::Report::outreach() callbacks

moved some LIMS::Base methods out to LIMS::Role::Base; new cron mail_reports.pl - shares some methods from LIMS; exempted http requests to Chart methods from authentication to allow mail_reports.pl script to generate charts
