umx 1.2.8

R 3.3.0 companion: "Very compatible" May 2016
NEW: umxRAM can now build and run Joint Continuous Ordinal models!!
NEW: umx_show_options function to help users learn the options available
BETA: umxACE can now implement a form of left-censoring.
BETA: umxThresholdMatrix can now implement a form of left-censoring.
IMPROVE: umxRAM & umxRAM2Ordinal can turn off reference models computation with refModels = FALSE;
IMPROVE: umx_show can show thresholds
IMPROVED: umx_is_MxModel can take a list: listOK option
IMPROVED: umx_check_parallel options for row-wise parallel and number of subjects
CHANGE: I changed "suffix" to "sep" in several places for consistency: this will break some low level code: nearly all of it mine, and fixed. But might affect some users!!
UPDATE: umx_time and umx_check_parallel to work with new S4 list deprecation
MINOR: umxTwoStage shorter run-time on 2-stage least squares

umx 1.2.7

May 2016 stable release
ADDED: umxTwoStage FIML-based Instrumental variable and Mendelian Randomization (beta)
ADDED: umx_make_MR_data to simulate SNP-based Mendelian randomization data (beta)
ADDED: umx_set_condensed_slots(TRUE|FALSE): Get and set matrix compression
ADDED: umx_get_OpenMx (download OpenMP/parallel version of OpenMx with NPSOL)
ADDED: umx_cont_2_quantiles(x, nlevels = )
ADDED: umx_factor alias to umxFactor
FIXED: plot(resid = "none") was not suppressing plotting residuals
IMPROVED: umxFactor now handles dataframes and allows non-ordered output
IMPROVED: umx_CI more flexible, now allows removing CIs
- Old code will break: replace "add" with "which"
IMPROVED: umx_time handling of no input arguments
IMPROVED: umx_pb_note better feedback and setup
IMPROVED: loadings() generic
CHANGE: umxModify - if free is a string, it will be used as input and the found paths will be freed.
CHANGE: umxModify - show summary as well when comparison = TRUE
CHANGE: plot defaults for std and showFixed changed h/t @MikeNeale
CHANGE: umx_scale_wide_twin_data argument names for consistency: "suffix" "data"
CHANGE: umx_residualize ditto.
UPDATE: "Read me" file.
