Merge branch 'master' of https://github.com/michaelhallquist/lavaan
allow for "|" operator in parseModelString
added 'varTable' in @Data@ov slot
add check for zero-nobs and zero-var variables
add auto.th and add threshold automatically if any of the variables are ordered
auto-remove variances/intercepts in lavaanify for ordered variables
adapted computeDelta to deal with thresholds
adapt computeGradient for thresholds
adjust independenceModel to deal with categorical data
added ULS estimator for categorical data
add DWLS estimator for categorical data
added robust standard errors for DWLS, WLS and ULS (robust.wls)
added WLSM and ULSM estimators (test="mean.adjusted")
added WLSMV and ULSMV estimators (test="mean.var.adjusted") (Mplus<6 style)
added WLSMV and ULSMV estimators (test="scaled.shifted") Mplus 6 style
WLSMV estimator (DWLS + robust.wls + scaled.shifted) is now default if data is categorical
add 'mvtnorm' dependency in DESCRIPTION
