Error Estimate in Summary is wrong, so is $Hessian

It seems that the diagonal of the $Hessian results returned are used as the Error Estimate in summary. Running the homepage model, pathic version we get:

name matrix row col parameter estimate error estimate
1 A 1 6 0.39715247 163.52372
2 A 2 6 0.50366153 149.57542
3 A 3 6 0.57724183 141.16243
4 A 4 6 0.70277427 125.43848

Doc Fixes

Clean up the three images in SimpleReg, MultReg and MultiReg:
-keep the notation of (particularly intercept) terms consistant with text
-make parameter notation text bigger

Give Hermine some bug reports.

dataColumns slot is ignored in FIML

The script models/failing/MultipleRegression_MatrixRawReverse.R is identical to models/passing/MultipleRegression_MatrixRaw.R except the 1st and 3rd columns of observed data have been switched (along with their column names). The dataColumns slot is assigned c(2,1,0) in MultipleRegression_MatrixRawReverse.R, but the correct answer is not being computed.

Relax nrow and ncol reguirement for Full matrix.

When the user provides vectors as arguments to mxMatrix() and type is 'Full', only one of nrow and ncol is needed. This fix applies only to 'Full' matrices. The following matrices are all square: "Diag", "Iden", "Lower", "Stand", "Sdiag", "Symm". And "Unit" and "Zero" need both row and column information.

Update ACE model in documentation

The following model has been updated in the /demo directory, but not in the documentation. The AE model should be created by modifying the sub-models. On the documentation page, currently the super-model is being modified to create the AE model (this doesn't work).
