 - bugfix:      readModels now detects filefilter arguments that use $ or ^ to denote the end or beginning of a string, respectively, and also handles ".out" being included in filefilter Addresses #194.

Version 1.1.2
 - bugfix:      Break file paths > 90 chars in prepareMplusData and mplusModeler to avoid line length errors

Version 1.1.1

Version 1.1.0
 - bugfix:      fixed a bug in handling multiply imputed data introduced in 1.0.0 
 - bugfix:      In readModels, $data_summary now contains cluster-level information for THREELEVEL models. Fixes Github Issue #18.

Version 1.0.0
 - notice:      Most functions are now quiet by default. Functions now print less messages/output to the console during regular runs. This can be changed using the new quiet argument available (e.g., in readModels(), mplusModeler(), etc.). Thanks to cjvanlissa for the pull request.
 - notice:      The default of SummaryTable() is now "none", to prevent accidental printing to console. Thanks to cjvanlissa for the pull request.
 - feature:     There are now more informative error message for mplusObject() without results section. Thanks to cjvanlissa for the pull request.
 - feature:     Add methods for mixturesummarytable for all types of MplusAutomation output. Thanks to cjvanlissa for the pull request.
 - feature:     Pass arguments for mplusObject() and mplusModeler(), specified through createMixtures(), on so that users can fully customize these calls. Thanks to cjvanlissa for the pull request.
 - feature:     prepareMplusData() now handles multiply imputed data. Thanks to cjvanlissa for the pull request.
 - feature:     mplusObject() gains arguments modelout and dataout, which makes it easier to create a list of model objects. Thanks to cjvanlissa for the pull request.
 - feature:     There are new convenience functions, get_*() to extract all first-level results from mplusObjects(). Thanks to cjvanlissa for the pull request.
 - feature:     Table sorting is more robust and there is a new argument, sortBy = NULL to avoid sorting. Thanks to cjvanlissa for the pull request.
 - feature:     Unit testing has been added to check that a variety of Mplus User Guide examples are read in correctly.
 - feature:     readModels() now returns the entire raw output file. This means that R objects from Mplus can be saved and contain all needed output. Mplus text input/output files do not need to be kept for a complete record. The raw output file is stored in the $output list element.
 - feature:     MplusAutomation now tries harder to find an Mplus (or Mplus Demo as a fallback) command in an OS independent way thanks to new function detectMplus(). This takes over the default Mplus_command argument in runModels() and mplusModeler(), which should mean it works more often, on more platforms, without users needing to specify the command/path to Mplus.

 - feature:     prepareMplusData now is more efficient at converting datasets to numeric and  utilizes fwrite to increase speed of writing out datasets (closes issue #54).
